This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

Hotpoint Ultima washer showing F05 and not refilling or spinning

The problem
A Hotpoint Ultima washing machine showed error F05. After the filter was cleaned and a coin removed, the pump worked again, but the machine would not fill or spin and the programme time counted down.
Likely cause
The accepted reply says F05 indicates the pressure switch is stuck or being held on. The most likely cause given is a pressure system fault, especially a blockage in the pressure chamber bottle connected to the thin pressure tube, or a jammed pressure switch. Connection issues or a PCB fault were also mentioned as possible but less likely.
What fixed it
The accepted diagnosis was to investigate the pressure system rather than the pump if the water is pumping away correctly. Recommended attention was focused on the pressure switch and the pressure chamber/tube for blockage or sticking. The exact repair carried out was not confirmed in the discussion.
Checks to try
  • Filter cleaned
  • 29p coin found in the filter
  • Pump reported working again after cleaning
  • Machine then would not fill or spin
  • Programme minutes counted down
  • Accepted reply states that if water pumps away OK, the fault is likely elsewhere in the pressure system

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Error F05 means the pressure switch has "jammed" on preventing the signal that the water has pumped away successfully. This can be caused by a pump blockage, but if so, it should have a lot of water in.

If the water pumps away OK, but you still get this error then it's not a pump blockage, it's a fault elsewhere. Suspects are the pressure switch itself is jammed, (i.e. the switch is stuck), or it's jammed on because a blockage in the pressure chamber bottle at the bottom of the thin tube which is connected to it is holding air pressure keeping the pressure switch on. Could even be connection issues or pcb issues but pressure system issues is most likely. Theres a lot on pressure systems in these forums if you search all forums for "pressure system".
