Control is programmed to
stop running and not allow any further cycles if it detects a water
heating problem (no temperature increase detected in heated Main Wash
cycle or in 3 consecutive cycles on the latest software version).
Control blinks the Clean LED 7 times repeatedly and disables the
Start/Resume key until cleared. |
Running Diagnostics
clears the control and allows it to
operate again. The water heating condition must
be corrected or the control will stop running again. See potential
causes below. |
|
Check If…
Heater circuit problem:
♦ Open heater.
♦ Wire
disconnected, open connection or component in heater circuit.
♦ Faulty heater
drive circuit on control. |
Then…
1. Check operation of
heater in Diagnostics cycle.
2. Unplug dishwasher or
disconnect power.
3. Check resistance of
heater and all components and connections in the water heating circuit
or heat dry circuit. |
|
Door switch not making
contact consistently:
♦ Misaligned door
latch assembly (which can be aggravated by high door closure force
keeping strike plate from fully seating).
♦ Faulty door
switch (high resistance).
♦ Loose or missing
installation anchor screws, causing tank to shift in cut-out.
NOTE: Neutral switch on
plastic tub models is only in series with the heater; other loads are
not affected. |
1. Unplug dishwasher or
disconnect power.
2. Measure resistance of
door switch contacts while checking mechanical operation of latch
assembly. Confirm switches not loose from assembly. Check strike plate
and door closure. |
