Indesit WIE 137 UK showing F03 after sensor and wiring checks

The problem

An Indesit WIE 137 UK washing machine repeatedly showed fault code F03. The owner had already stripped the machine down, replaced the temperature sensor/thermal limiter, checked continuity of the wiring from the sensor to the PCB, removed the PCB and cleaned the contacts and board, but the fault remained.

Likely cause

The discussion most strongly supports an NTC/thermostat circuit fault associated with F03. As the sensor had already been changed and wiring/connections checked, the remaining suspected cause was the PCB, although contributors stated there was no guarantee a replacement PCB would cure it.

What fixed it

The only further action suggested was to recheck NTC and PCB connections for broken wires internally and then consider replacing the PCB. The exact repair was not confirmed because the owner did not proceed and instead bought a new washing machine.

Checks to try

• Replaced the temperature sensor/thermal limiter
• Checked continuity on the wires from the sensor to the PCB
• Removed the PCB
• Cleaned PCB contacts
• Cleaned the PCB board
• Checked items referenced in the F03 guidance link
