F24 Heater relay contact
The program is interrupted and the drain pump is operated.
The display shows Technical fault F24.
Call the Service Department.
The buzzer is activated for 2 minutes.

Background information:
When the circulation pump is not operating, the heater relay contacts are checked. If supply voltage is then applied to the electronic’s inputs, the fault is registered.

Cause:
Heater relay contacts have fused together.

Remedy:
Replace the heater relay.

Cause:
Moisture in heater relay.

Remedy:
Replace the heater relay.

Cause:
Fault in the plug on the exit side of the heater relay. Contamination on the plug of the heater wiring harness causes resistance values between the contact blades to fall below 10 megaohms (10M?).

Remedy:

1. Disconnect the appliance from the power supply.

2. Disconnect plug 5 from the electronic.

3. Measure the resistance between the lines of the electronic for heater pressure switch B1/13 (pins 12 and 22 on plug 5).

4. If the measured resistance value is smaller than 10 megaohms (10M?), then the heater wiring harness must be replaced.
