Grundig GWD59400C shows ‘Safety’ and shuts down during drying

The problem

A Grundig GWD59400C washer-dryer washed normally, but on any drying programme the display showed ‘Safety’ after about 20 minutes and the machine shut down roughly 30 seconds later.

Likely cause

The accepted reply said the fault was likely in the drying section and may be due to overheating. Possible causes mentioned were failure of one of the drying processes: heater operation, drum rotation during drying, dryer fan running continuously, or the required trickle of cold water for condenser cooling.

What fixed it

The recommended action was to confirm the machine was connected to a cold water supply with the supply left on during drying, then observe the drying cycle to check that the heater operates, the drum turns, the dryer fan runs continuously, and cold water trickles into the condenser chamber. Because the appliance had been transported, the advice was to isolate it from the mains, remove the lid, and check whether anything had come loose, including fan wiring. The exact repair was not confirmed in the discussion.

Checks to try

• Confirm cold water supply is connected and left on during drying
• Observe whether the heater operates on the drying cycle
• Observe whether the drum turns on the drying cycle
• Observe whether the dryer fan runs continuously
• Observe whether a trickle of cold water runs into the condenser chamber during drying
• With power disconnected, remove the lid and check for anything loose, including fan wires
