Ancient Kenmore washer won't drain or spin
« on: May 13, 2011, 07:47:50 PM »
Hello

I have a Kenmore washing machine circa 1978. It will fill and agitate for the wash cycle but when it gets to the rinse cycle it will not drain or spin. The timer still advances and the motor (pump?) makes a humming noise like it is trying to run. When I left it too long I smelled a faint burnt rubber smell.

I emptied the clothes and then bailed out most of the dirty water. There is still a bit of water left and it still won't drain.

I really like this washing machine and I would like to know if it is possible to repair it.

Thanks!

Here is a picture of the ID tag on the machine (I don't know which is the model and which is the serial number)


Model FM15975

This washer has a motor on it that goes on one direction only. To go from wash to spin the timer powers up a solenoid mounted on a wigwag. It is called a wigwag because it wigs and wags back and forth all during the wash cycle. The belt (factory specified part number is 95405) could be worn out. When the wigwag solenoid is activates it grabs a rod and shifts the gears inside the tranny and it yanks a lever on the pump that operates the flap inside the pump. When that flap get open them waters gets pumped out the machine. Now yall might have a bad pump or pump flap or a worn out belt or the wigwag itself has an open coil on it. The interesting thing yall can do with this washer swap the wires on the wigwag and the timer will actually wash in spin and spin in wash. Their 4 wires on the wigwag. 2 white wires which are common and need not be touch , the other 2 wires get swapped and she works backwards. So if it spins in wash when the wires are swapped then their is a timer problem. But if it don't then the wigwag is bad. You can always ohm em out too. Sometimes the shafts on the shift rods get rust on them. When the coils are activates the shift pins won't budge. yall can sand them down and re install them and it might work without even buy any parts. Seen it. The lid switch is tied into the circuit to the spin solenoid so if the lid is open the wigwag will not activate the solenoid and the washer will not spin or pump out.

Wow JWWebster, thanks for the reply!

I forgot to mention that I did have the timer reconditioned about 2 years ago because it would stop halfway through the rinse cycle. I could advance it with my finger but it wouldn't go on its own. When I got the timer back the machine worked as good as new ever since. So, it might not be the timer.

I will take the back off the machine tomorrow and look inside. I'm not familiar with any of the parts (I'm a girl - but not afraid of a screwdriver :) but maybe I can see if the belt is worn etc.

I did manage to drain the rest of the water by taking the drain hose off the laundry tub and placing the end in a low pail. So I do know the drain hose is not plugged.

I will let you know what I find tomorrow. I'm so glad someone is familiar with my old machine! Thank you!

I'm an old fart like JW . Used to repair tons of "wig wag " type washers .Upper class techs would call them control magnet assemblies LOL . Remember what would happen if one of the wires to the wigwag would make and break as the wigwag was moving back and forth . Another issue was the timer would stall out just before spin . A third problem was the set screw would back out of the BB&D causing the brake to stay on so no spin . Those washers had more steel in them than some present day cars .

No kidding - these things (I have the dryer also) are extremely heavy and a bear to move! But it says heavy duty on the front and it meant it. :) 33 years later..

Now that I think about it, when the agitator was.. er, agitating, I don't think the drum was moving back and forth. I think normally the drum part moves as the agitator does, but I don't think it did that this time. I do know it definitely did not spin.

During agitate the wash tub does not move, it is held by the brake . If the drum moved while it agitated you would have a tangled mess of clothes.

Hi RAH52, okay that's good, so the wash cycle was working properly.

I took the back off the machine and the belt is intact. I was able to pull on the belt and move it to the left and to the right - it was equally easy to move in both directions.

There are 4 wires visible underneath - 2 white, one yellow and one red. I know the yellow one is for agitating because it used to slip off and then my agitator wouldn't work. All the wires looked intact and were plugged in securely.

I couldn't tell what the water pump was. If I post a photo can someone give me a clue what to look for?

With the machine unplugged take the red wire off and tug on it a little bit. They would quite often break inside the insulation. U can also watch while someone turns the machine on in spin cycle & see if plunger on red wire side engages. If so possible bad pump. Loved those machines but glad to see them go. too old to tug on them now.

You might simply have something stuck in the drain pump.
Lay the machine down and remove the pump.
Check inside for a blockage.
While you have to pump off,replace it.
