Washing Machine stops on long cycles

Indesit Innex washer dryer shows F01 on longer wash cycles

The problem

An Indesit Innex washer dryer ran the 45-minute quick cycle, rinse and spin normally, but on programmes longer than an hour it stopped around 20-25 minutes into the wash with F01 and flashing lights. The clean cycle also reportedly produced foam. The pump had already been checked and the machine was said to fill and drain normally.

Likely cause

The accepted reply said F01 indicates a motor triac fault, with possible causes including a motor fault, poor electrical connections, or a fault on the PCB chip. The repeatable failure point during the drain stage was noted, but no conclusive component-level diagnosis was confirmed in the thread.

What fixed it

No repair was confirmed by the original poster. The accepted advice was that this did not sound like a straightforward DIY fix and would likely need further diagnosis of the motor circuit, wiring connections and control PCB by an engineer.

Checks to try

• Pump checked and reported as fine
• Machine fills and drains normally
• 45-minute quick cycle works
• Rinse and spin options work
• Fault occurs consistently about 20-25 minutes into longer wash cycles, during or around the drain stage
