Hotpoint ultima dishwasher h2o error code

[alelym]

We have an error message (h2O) on our Hotpoint dishwasher SIUF 2211P ULTIMA, I have checked the water feed connection which is working and the filters on the end of the hose (within the grey connector block)
but they are clean and not blocked.
I note there is an electrical valve /motor within this grey connector block which is sealed up and I cannot see a way of testing it to see if it’s working

Any idea if it’s this part which is the faulty or is there another sensor or motor/pump component part which could give this error code?

Any help would be welcome

Re: Hotpoint ultima dishwasher h2o error code

all this means is the machine cant sense water. it could be the valve or the sensor for the water

when you run on a programme it should
1 pump for a bit
2 start filling

if it start to fill and you can hear water going in its a good chance its the sensor but you cant prove in unless you replace it

Thanks, yes it does sound like its going to fill but stops as soon as it starts, were abouts is the sensor fitted, any idea if there a part name for it ( ie fill sensor) or part number
Thanks
