Indesit WILX 123 stops before spin and shows flashing light fault linked to pressure system

The problem

The washing machine would run until the fast spin stage, make a few attempts to spin, then lock out with a flashing red light and option lights reported as 2 and 4. Later, the machine also filled briefly, stopped, locked out and drained the water, with the lights then reported as 2 and 3.

Likely cause

The accepted diagnosis was F05, indicating the pressure switch circuit was staying in the 'full' state, most likely due to a blockage in the pressure system or pressure chamber, or less likely a faulty pressure switch or drain/pump blockage. The later recurrence after blowing through the tube again supports an intermittent blockage in the pressure switch hose/pressure chamber area rather than a confirmed electrical fault.

What fixed it

The pressure switch hose from the bottom of the machine to the pressure switch was removed and blown through, then refitted. This restored operation initially. Further advice was to check for a small blockage in the pressure chamber at the bottom of the tube and clean it properly if blocked. Exact permanent repair was not confirmed.
