Indesit IWDD7143 shows F13 during Express Wash & Dry drying stage

The problem

On an Indesit IWDD7143 washer dryer, the drying part of the Express Wash & Dry programme stops after two or three minutes with fault code F13. Dry-only cycles and drying after other wash programmes were reported to work normally. The NTC sensor in the heater assembly had already been replaced, and the fan had been cleaned due to fluff build-up.

Likely cause

The accepted reply linked F13 to a faulty dryer NTC circuit or the dryer fan not running. As the NTC had already been replaced and the fault only appeared on the combined Express Wash & Dry cycle, the strongest supported possibilities were a connection issue to the NTC, the fan not running correctly during that specific drying stage, or an airflow/condensing problem causing overheating, including blockage in the condenser chamber or no trickle of water into it.

What fixed it

Recommended action was to check the NTC connections, confirm the fan runs when the machine enters drying after the wash cycle, and inspect for blockages in the condenser chamber. It was also advised to make sure there is a trickle of water running into the condenser chamber during drying. The thread was marked solved, but no final confirmation of the exact repair was posted.

Checks to try

• Replaced the NTC sensor in the heater assembly
• Cleaned fluff build-up from the fan
• Check the NTC connections
• Check whether the fan is running when drying starts after the wash cycle
• Inspect for blockage around the fan and in the condenser chamber
• Check for a trickle of water running into the condenser chamber
