I have the same problem, the machine is about 2 1/2 years old. lol !
Found this thread (and another) while searching for a solution.
Actually to give some more detail, put the machine onto wash and things seemed fine.
At some point in the wash the machine stopped, some hours later when i revisited machine it was displaying fault F01.
Fault "F01" is a "motor fault" according to the internet searches.
That was fine, switched machine off, this cleared the faults and attempted restart.
This time the error message read "no water, check supply".
Sound familiar?
Anyways,
Had the machine off overnight and attempted restart next day, it worked, went through it's cycle without any problems.
Problems arose when it was tried on the next wash, again "no water, check supply".
Got the machine to work a few more times by removing power overnight but eventually it died.
Thankfully, the final time it died the error message "F01" was highlighted, left this on so that the engineer could see it for himself.
Only seen this error massage twice throughout the days that I had this problem.
During the few days that these faults were occuring did some checking of individual components.
Obviously checked water supply and was happy that it was ok.
The water valves, there are two on this machine to direct water into the different detergent compartments,were checked.
Coils seemed fine, if i recall correctly they were reading about 4.7kohms.
The motor on this particular machine is three phase induction.
Got the multimeter again and checked coils, obtained reading of 6.2ohms and balanced.
Infinity to earth.
Didn't check the door lock and when it clicked shut (or should I say locked) could see the small key symbol on the digital display,
I'm assuming this is feedback from the lock,as the the correct position of the lock ?
Water sensor not checked
Anyway, that was about it for testing, not much else in there apart from the control board.
Had priced one of these but not only do you need the board, you need the programmer and a program.
Getting a bit much.
Got in touch with hotpoint, sadly they quoted higher prices than those posted by andy6581
Gave me two options,
1. fixed price repair, with a 90 day warranty on the repair, for £130 or there abouts.
2. fixed price repair, with a 1 year warranty on the full machine, for £150.
After considering a repair, new cheap machine, new expensive machine, went with the repair.
The hotpoint service man arrives, does some quick checking, and concludes that it is the control board at fault.
This was duly replaced, programmed up and test ran through various steps.
All in all he was at the house for about 30 mins (the machine was already out with panels removed ready for any component checking).
Job done and have the machine doing some overtime just now.
Hope this information helps anybody else who finds similar faults.
