Controls timing out and showing “1”

Fault Diagnostics

To check the heater, turn off the dishwasher, block up the tank and check the resistance of each part of the heater as follows.

Heater ~ 11 Ω

Hi-Limit ~ .3 Ω

Flow switch ~ .4Ω. A spring loaded plunger closes it when water is flowing, so you must remove the microswitch from the heater and close its contacts to measure the resistance.

TIP: Current can be measured through the red heater wire at the control or heater (~ 9.5A). There can be more than one red wire, so check the wiring diagram to select the heater wire.

NOTE: Open door to run test program.

Controls timing out and showing “1”

Occasionally dishwashers can run for hours, not finish washing & show a “1” in the display. This means the module has timed out due to an unidentified heating problem --all heating related parts must be checked until the problem is found.

Heating system checklist if controls time out:

Check control module heater relay & solder joints.

Check wire harness & terminals (to control and heater). Controls have been replaced when the problem was loose connections.

Check heater resistance (~ 11).

Check flow switch (~ 0.4). If flow switch is OK & water doesn’t flow, check circulation pump.
