How to repair direct drive washing machines?

This applies to both their Washing Machines and their Dryers. What compounds this problem is the fact that most of these failures are catastrophic, expensive, and a major parts replacement headache.

Nobody wants to buy a Washer or Dryer that has an average lifespan of 6 months to 2 years, and that is what most of us end up with these days.
This isn't entirely the manufacturers fault however. In an effort to please their customers, many manufacturers try to add innovative features and advancements which make your appliance more user friendly. The competition is often tough and heated with the end result that the manufacturer is often rushed, to market a machine that competes equally with it's name brand rivals.

The case for Front Loading Washing Machines

If you own one, or have owned one in the past, I won't surprise you with the statement that these are the most problematic and troublesome machines in this field. Front Loaders are prone to leak from their silicone aprons, burn out their rear bearings, slip off of their suspension brackets and kill their own motors and brains.

Direct Drive Washing Machines consist of 4 distinct parts.
The pump, the motor, the coupling and the transmission.
All of which can be disassembled and replaced by the least educated among us with very little difficulty.
Basically, if you can change the oil and filter in your car, fill your own dishwasher or de-lime your Mr. Coffee, you have all the skills you need to fix your OWN Direct Drive Washing Machine.

Tools required

1. A standard Flathead Screw Driver (Motor and Water Pump Retention Clips)
2. Water Pump Pliers for hoses (Channel Lock Pliers will also work)
3. A 1/4 inch socket and Handle, or 1/4 inch nut driver.(Motor Nuts)
4. A 9/16 to 5/8 inch socket and 3/8 inch ratchet (Transmission)
5. A 3/8 Socket and 3/8-8 inch extension plus 3/8 ratchet (Agitator)
6. Phillips Screw Driver

Symptoms and Cures

1. Symptom: Leaking water from the front of the washer

Cure: Tighten the Water hoses(Tools #2) to your machine or Replace your water pump (Tools, #1, #2 ) Remove the retention clips that hold your pump to the motor. Squeeze and slide your water pump clamps away from the water pump and remove the hoses, then replace the pump.

2. Symptom: Washer drains the water, but fails to spin or agitate.

Cure: Replace the Lid Switch (Tools #6)

or Replace the motor coupling located directly in front of and attached to the motor by removing the water pump (Tools, #1, #2 ), hoses, then the water pump Retention clips (Tools #1) then the nuts holding the motor clips down (Tools #3).and finally the clips holding the motor (Tools #1).

Pry the plastic tripod shaped plastic piece from both the motor and the transmission (Tools #1) and throw them away along with the Rubber cushion between them. Replace the Tripods with the new coupling partsexactly as they were before removal. The plastic tripods will be tight so you can tap them down flush to the motor shaft and transmission to seat them in place. Replace the rubber dampener on the transmission taking care to match the motor tripod to the empty teardrop shaped holes and seat the motor back in place then clip it all back together. I never replace the screws since they make no difference at all when locking the motor down. The clips are more than enough to keep this all together.

3. Symptom: Washer fills with water, but doesn't spin, agitate or drain, and no motor noise is heard

Cure: Again this may be a lid switch depending on the year and model (Tools #6) or it is the Start upcapacitor (Tools #3 or #5). The capacitor is usually a long 4 to 5 inch black to brown cylinder with 2 electric leads recessed into the head. It is located in one of 3 places. In the head and timer area, Mounted to the back inside wall of the machine or Screwed directly on the motor with a circular bracket. You can usually remove the capacitor easily if it's mounted to the inside wall or the motor. The head/timer area will require you to remove 2 Phillips head screws (Tools #6) slide the head forward and unhook it from the base of the machine.
The capacitor may either be mounted in the head itself, or the top of the steel base.

4. Symptom: Motor spins, water fills, pump drains water, lid switch activates the motor, timer hums but washer neither agitates or spins.

Cure: Replace the transmission.(Tools # 1 through #5). there are 3 bolts that hold the transmission in place, as well as the nut that holds the agitator in place.

I usually remove the agitator bolt first,


then tip the Washing Machine 60 degrees on it's back to access the transmission for this repair, then I remove the wire loom attached to the motor as well as the capacitor if it is screwed to the motor. Then remove the wires from the small plastic loop that locks the motor wire loom in place on the transmission. Next, remove the 3 bolts that hold the transmission to the machine and slide it out without bending the agitator shaft. Replace the transmission with a used or new transmission that exactly matches the old transmission agitator shaft length. Assembly is the exact reverse of disassembly.

5. Symptom: Washer does exactly what it is supposed to do, except that when the lid is opened, the tub makes a howling or grinding noise, and sometimes a shrieking or whistling sound, followed by a burning smell.

Cure: This is caused by the Tub Brake (Clutch) which is located directly on top of the transmission and has a loose rubber noise dampener ring attached to the outside of a shiny silver/chrome looking wheel. Inside this wheel you will find a circular ring with a spring and 2 dog eared bends in it like this /.

This piece is the actual brake (Clutch) shoe, and if every other hole on that shoe does not have a white pad riveted to it, your brake has either begun to fail, or has already failed completely. Replacement is easy, just grab your pliers, squeeze those 2 dog eared bends together and lift it out.
When you install the new one, be careful sliding the transmission back on because there is a white plastic cam on the drum that must be free spinning to activate the brake.


This cam must not rest between the Dog ear bends "/ ( a common mistake) but to either side of them " / or / ".

6. Symptom: Lower Agitator rotates, upper agitator spins freely, Clothes are still dirty.

Cure: Replace your Agitator Dogs.


This is a typical agitator dog replacement kit above, but in most situations, you will only need the 4 beige dogs you see in the picture.
You will need to remove your Agitator bolt to release the agitator assembly. Then you will need to pull the large white piece as seen at the top of the photo straight up to access the dogs directly. Most of the time the entire top half of the agitator breaks free, so don't get excited, this is to be expected. Replace the dogs in the slots provided exactly as they came out with the teeth grabbing the inner rim of the agitator. Then reassemble and bolt in place.

For NO-SPIN problem on top loader washing machines, this will help:--
Whirlpool manufactured direct-drive TOP LOADING washers with a no-spin problem. This includes Kenmore, Roper, Estate, and certain Kitchenaid, Kelvinator and Maytag models.
The most common source of a no spin problem can either be attributed to a broken motor coupling, or a lid switch malfunction.

MOTOR COUPLING:

If the washer will fill and drain, but won't agitate or spin, you may have a broken motor coupling. The noise of the motor engaging, lack of agitation and ability to still drain are the usual symptoms. This is a common fail item with this model washer through normal wear and tear. Newer versions of the coupler are more resilient and resist breaking.
The motor coupling is located between the drive motor and the transmission and takes the place of a drive belt. This configuration is known as a "direct-drive" system. They do wear out and can break.
LID SWITCH:

If the washer fills and doesn't do anything, or stops right after the wash cycle and won't advance to the rinse cycle, this is commonly caused by a lid switch malfunction. The washer usually will NOT drain either. The lid switch is usually mounted under the washer top casing, on the right hand side on most top load models. It is activated by a plastic piece on the lid (called a "Lid Strike") through a small hole on the rim of the wash tub opening. In many cases the lid strike breaks off the lid, or the lid switch becomes loose and no longer makes contact. Inspect the lid to make sure the lid strike is still intact, and then inspect the mounting screws (adjacent to the small opening on the wash tub rim) and make sure they are snug. If you determine the switch to be defective, then replace it.
On some models, the lid switch is located under the top casing by one of the lid hinges. You will know if you if you have this type of switch, because It does not have a lid strike and the small hole on the right hand side of the wash tub will not be present. This switch is actuated (toggled) by a rod on the lid hinge. With this type of switch, if you locate it and it can be toggled by hand, you may only need to adjust the actuator by bending it slightly. The average price for a replacement lid switch is $20 - $30.

Dishwasher fills with water even after turned off?

A dishwasher filling with water overnight or when not in use has two possible causes. Either the water is running into the washing machine from the sink (if the drain hose is connected directly to the sink) or one of the water valves isn't shutting off properly and water is dripping slowly but surely into the washing machine. The latter problem can take several hours before the water level rises high enough inside the washing machine to be visible.

It's easy to track down the cause of water entering the dishwasher when not in use. If turning off the hot and cold water taps stops it, then it's one of the water valves not shutting off properly, and needs replacing. With a hot and cold fill machine it's just a process of elimination to find out which one it is.

If you have a problem with your washer or dishwasher continuing to fill with water even after the valve has closed.
Then read the following :---

If you are working on a dishwasher then the valve that is causing the problem will probably look something like this, and will be located under the dishwasher where the water connection is. This is what the valve looks like if you take it apart to clean it. If the right kind of dirt, like sand gets through the screen and gets embedded in the seat of the valve, it will hold it open slightly, causing it to leak.

By taking it apart you may be able to get the debris out of the valve seat and get it to close fully again.

If the water does not even slow up when you unplug or turn off the power, then the valve has totally come apart inside and cleaning it will not help you. You will need to replace the valve if that happens.

Washing machine valves are very similar, but are a double valve, one side is hot and the other is cold. If you have water running in your washing machine, when it should not be, then you need to determine if it is the hot or the cold water that is running. Then you can also possibly fix the washing machine valve by taking it apart and cleaning it also, just like the dishwasher valve.

Some of the newer washing machines may also have valves that look very different because they mix the water to a temperature as it is going in. If you have one of these valves they are much more complicated to take apart to clean. If you try to take one of these valves apart, pay very close attention to how it comes part so that you can get it back together again.

The main thing to remember when looking to find out why the water will not shut off going into yourdishwasher or washing machine, is that the electrically operated valve may not be able to shut off completely if there is debris caught inside the valve. Finding out if the valve closes some, but not completely will tell you if the problem will require just a cleaning or a complete replacement of the valve.
