Hi Because the timer controls many operations, a faulty timer can cause many problems. The timer is a complex component, so you shouldn't attempt a do-it-yourself repair. Test the timer with a VOM set to the RX1 scale. To gain access to the timer, remove the front control panel. The timer is directly behind the main timer control knob. Disconnect one of the timer's terminal wires and clip one probe of the VOM to each terminal. If the meter reads zero, the timer is working. If the meter reads higher than zero, the timer is faulty and should be replaced. 

If possible, use the same procedure to test the selector and cycle switches. The wiring hookup, however, may be too complicated to figure out on either of these switches. If you aren't sure you can deal with these switches, call a professional service person. Replace a faulty timer -- or a faulty control switch -- with a new one made for the dishwasher.

The timer is connected to several wires that supply power to operate the various functions of the dishwasher. To replace the timer, have a helper hold the new timer next to the old one. Connect the wires of the new timer one by one, removing the old wire and connecting the new, to make sure you connect the wires correctly. The wires may be friction-fit on the terminals. If they are, use long-nosed pliers to remove the wires. Don't pull up on the wires, or you may break the connection between the wires and the clips. 

After connecting the wires, set the new timer in position, secure it the way the old one was secured, and replace the control panel and knobs.

I have a whirlpool Quiet partner 1 (DU920PWKQ0) that sticks midway thru the wash cycle and continues to wash until the control knob is physically moved, how do I repair this? Thanks


Try to clean the timer assembly using electronic cleaning chemical and ensure the base where the knob rests is also free from sticking.Replacing the timer is the best

Wash cycle knob


It's a quirk of the cycle timer. You can replace the timer ($) or live with it. Besides, a replacement might have the same quirk

Hobart LXIH stuck in Wash mode after running multiple loads. Shutting off breaker for several hours fixes problem until multiple loads have been run again and then it is once more stuck in Wash mode.


How long does it stay in the wash cycle? Indefinitely? Does the display continuously show "WASH"?. If it stays in the wash cycle indefinitely (i.e. continuously shows "WASH" for significantly beyond approx. 3 minutes), it's probably a control board malfunction. If it continues to wash after the "WASH" indicator goes out, it could be a shorted wash motor relay on the relay board or a fauly control board.

If the internal rinse water booster heater doesn't reach it's programmed setpoint temperature in time, the dishwasher will run an extended wash cycle to give the booster heater more time to finish heating the rinse water. If this is what's happening, the wash cycle would last approximately 3 minutes, then it would rinse regardless of whether the booster heater has finished heating or not.

The booster temperature thermistor may be bad, giving a false booster temperature reading, causing an extended wash cycle as described above. The booster heater elements or contactor may be bad, preventing the booster heater from heating and reaching proper temperature, also causing the same extended wash cycle to give the booster more time to heat.

STICKS on cycle, wash, etc. If manually moved


Do you mean the timer or control dial sticks. If so then it may be the timer mechanism itself.

Make sure that when you are skipping a turn on the timer that the machine is actually performing that particular task of the cycle. For example if the timer gets stuck before the drain cycle, and you manually skip forward to it, that it actually drains the water out.

If so then it is most likely a worn timer mechanism which sticks.

Dishwasher doesnt drain on wash cycle,ok on rinse cycle


Change the circuit board, timer/progrsmer.
Take it out and clean contacts,
Look for burnt circuit line and solder a fine bead carefully on the circuit board, difficult. Use the pot and pan program.

Bosch dishwasher timer sticking


I have been told to replace the timer which I am looking to do the same to my machine!

Dial Timer sticks between wash or rinse modes


Hello. Is the water getting hot? Usually the timer won't advance because it isn't getting a signal from the thermostat that is on the bottom of the tub, so it thinks that the water isn't hot enough to go through the rest of the cycle. That is if the water is hot. If it isn't hot then you may need a new heater. You may or may not need a new timer. Try the thermostat first because that is usually the thing that goes out and it is less expensive than the timer. You can order it from www.coastparts.com or www.marcone.com .
Let me know if you need anymore help.

Does not advance to drain cycle


I would bet that it is the timer switch assy.
Motor runs ? yes
washes? yes
drain tube clear ? yes

If there is no drain valve to deal with, the problem must be the contacts during the timer cycle, since the main obviously works or you wouldn't be able to wash anything.
you need a new timer switch assy.
