If your hotpoint washing machine is not working and you feel it needs repairs and you are getting the E10 or F10 error code, this means there is NO cold fill and you should check and verify that the taps are on and that the hoses are not kinked.
The first thing to check is the taps, most machines will have the hot and cold fill supply plumbed via a hot and cold inlet valve placed under a sink or directly behind the machine, it is usually a silver valve with the Blue and some times a red flexible hose connected to it, the blue should be cold and if there is a red that will be the hot supply.
In the on position, the plastic switch located on the side of the in let vale should be pointed in the same direction as the arrow on the valve and in the off position it should be pointed across the valve, if it looks off, especially if your valve is under a sink where pots, pans, boxes and other item can get pushed up against it and could turn it off by accident, simply turn it back on, but do not force it, as forcing it could break it, and that could lead to a flood situation.
If the valves looks OK, but the washing machine is still not working and you still get the E10 or F10 error message, you now need to check for a kinks in the pipes, this will probably mean pulling the washing machine out from its housing to continue the repair.
At this stage you need to take in to consideration the fact that the washing machine will be heavy and connected to both the mains electrics and mains water supply and also that putting the machine back properly can often be harder than taking it out.
If you are unsure, you would be best advised to call a engineer, if you are not willing to pull the washing machine out you could still also check any part of the inlet flexible hose pipes that you can easily see, like in the cupboards and also to the side of the washer, if you see any kinks, you could try to remove the kink and test the machine again.
Error codes are usually machine specific and the diagnosis given here is for the hotpoint range only, do not relate this diagnosis or error code meanings to any other make of washing machine
