Replacement parts for WHIRLPOOL KUDS01DLBL2 Undercounter Dishwasher | AppliancePartsPros.comHer is the tech sheet
http://www.servicematters.com/d...0Sheet%20-%208537797.pdfchecked temp in bottom of unit throughout this time, as high as 126 deg, avg 123 deg, my owners manual says that cycle should be 120 deg, so water temp seems correct?
See the tech sheet for the temperature set points for the different cycle types. Am not sure if the above indicates that it is heating the water but it is very slow. If it is heating up but very slowly could be the water level is low, this is probably a dirty filter screen on the input side of the water valve. Also the heater is controlled by a triac, if half the triac goes out or it only gets on-pulses for half the cycle you will only get half power to the heater. It would measure approximately 60 volts AC.
Water temp at faucet right next to machine comes out at 125 deg. Does the " water heat lite mean the unit is not seeing the water temp? I believe it is indicating that the unit is trying to heat the water to the set point.
Is there a water temp sensor that could be at fault? Possible but more likely a water heating problem.
You could try the diagnostics.
Remove power from the unit and one wire from the heating element and measure it, should be approximately 20 ohms.
If OK
Remove one wire from the thermostat and check it, should be 0 ohms.
IF OK
Replace the wires and do a live test.
Check the voltage across the heater when it should be heating, should be 120 volts.
If OK
Check the temperature sensor for resistance, see the tech sheet.
Control panel fault, any known problems like this. Could be but there are other possibilities as listed above.
A jiggery pokery method for checking it, would be to add some boiling water during a fill, if it then skips merrily along you will know that the sensor is probably OK and it is a water heating problem. Just be careful not to overfill the unit.
If you do not own a meter, I would suggest you purchase a one. You can get a decent digital multimeter for under $20.00. You do not need fancy though it is nice if the leads are a couple feet long.
If it saves ordering one unnecessary part it has paid for itself and you end up owning a useful tool.
Most places will not let you return electrical parts so if you order it, you own it.
A couple things to watch when measuring ohms and continuity
1. Always remove power from the machine otherwise you could blow your meter.
2. Always disconnect at least one side of any device you are checking. This eliminates the possibility of measuring an alternate/parallel circuit path.
3. When checking for closed contacts and continuity use the lowest scale (Usually 200 ohms). Then try higher scales. This scale is 0 to 200 ohms so if the device you are measuring is 300 ohms this scale would show an open circuit which it is not, you are just measuring outside the scale's dynamic range.
There is a good STICKY at the start of this forum about it's use.
