Heating Element Earth Fault
If the heating element insulation breaks down, it can cause an earth fault that trips the RCD. Heating element replacement: £80–£150.
Pump Motor Fault
A developing fault in the circulation or drain pump motor can cause intermittent tripping. Pump replacement: £90–£160.
Water Ingress Into Electrics
A leak reaching the control board or wiring can cause a short circuit. The source of the leak must be identified and repaired before the machine is used again.
Wiring Fault
Worn or damaged wiring within the machine can cause an earth fault. An engineer can trace and repair the fault.
Is It Safe to Keep Using?
