The dishwasher is not heating up (DF967). Does anyone know if there is a
resetable limit thermostat that I should try first? I have found a
replacement heater is over £80 so I may be replacing the machine if it
isn't an easy fix.
The heater sits in a pipe in the side of the machine.


Checked the heater and it has continuity. Put volt meter on heater whilst
running the plate warming cycle - no volts present at first point of entry
to heating assembly.

Not ventured underneath the machine yet - any clues on what I should look
for? The two limit thermostats are okay on the sides of the heater.

Wiring loom or output from the controller then sounds like the next
likely targets.

Could you follow the wires back from the heater, and check continuity of
them to wherever they go?

If that design of machine has the wires passing through the door
hinge to a controller mounted in the top of the door, the conductors
breaking where they flex through the hinge is not unknown.

Also, whatever switches the heater current might have burned out
(mechanical controller and interlocks such as water pressure
sensor, or a relay).
