Our washer overflowed last night. no warranty on
Overflow is usually caused by a “stuck-open” fill valve, and the cold water half of the valve is usually the culprit.
This can also be caused by the fill system control components: pressure switch, pressure tube, or pressure tube dome/port.First of all, determine whether your overflow condition is mechanical
or electrical. Start the washer filling, then turn the timer off by
pushing the knob in.
If the fill continues, pull the washer plug. If filling continues with
the washer unplugged, you have a mechanical problem - nearly always a
stuck valve ***’y. Replace the fill valve.i
f however, the fill stops when you unplug the machine, you are
looking at an electrical fill control problem,
Here a small piece of rubber or plastic tubing is handy.
Unplug the washer and open the console where you’ll see the pressure
switch. This is the switch with a small rubber tube, usually clear,
sometimes black, attached.
Pull this tube off and replace it with your short tubing. Blow a bit of
pressure into the switch using your mouth, and listen for a click, then
another when you release the pressure. Hear two clicks? Good! The switch is probably OK, Plug the washer back in (being aware that components in the console
are now ‘hot’ and start the
washer filling again. With it filling, again blow a bit of pressure
into the switch. If the switch is good, the fill should stop and the
machine should start to agitate.
This verifies that the pressure switch is working, and causes us to
suspect the pressure tubing or a clogged port/dome to which it
connects. Wipe off the end of the original tube you removed from the
switch, and blow into it. You’re blowing air down into the tank now,
and you should feel very little restriction. If it is very hard or
impossible to blow through this tube, the tank dome or port is clogged..
Whatever your brand, if air can’t be blown back through this tube, the port or dome will need cleaning.
If you have no trouble blowing pressure through it remove the tube
completely and inspect it carefully. This tube must not have the
smallest hole in it, and we sometimes see them worn through or, more
often, chewed through by mice. while it is
the least common cause of overflow, it does happen and is easily
overlooked. sometimes this tube will swell and loosen a bit,
leaking air where it attaches to the tank fitting. If you suspect this,
or the tube fits very loosely, simply cut 3/4” or so off the end and
push it back on.
