Hotpoint WD440 F05 fault remains after pressure switch replacement

The problem

A Hotpoint WD440 washing machine was showing fault code F05. The pressure switch had already been replaced, and the filter, pressure tube and pipe had been cleaned, with connections also checked, but the fault remained.

Likely cause

The accepted reply says F05 is most commonly caused by a blockage in the pressure system. Other supported possibilities are a blockage preventing full emptying of water, including the pump, filter, drain hose or sump hose, or a pump fault. A faulty pressure switch was described as relatively rare.

What fixed it

No confirmed repair was posted. The accepted advice was that, if the machine had not fully emptied, the next areas to investigate were blockages in the pump, filter, drain hose and sump hose, or a pump fault. The exact repair was not confirmed.

Checks to try

• Pressure switch replaced
