Meile dishwasher puzzle

Irishmale

Meile dishwasher acting the Christmas idiot.
Giving an inlet and drain error f13.
Checked water and plenty going in. It's draining fine too with just a half inch left in the sump but it keeps throwing out the code at end of cycle. Filters clear, valves and motor clear.
It's won't clean glasses as well as it was either.
Has me stumped. Anyone any ideas?
Thanks

f13 is a filling error but you say it is filling, it should take about five ltr, you may have a dodgy water flow meter, check the filter at the tap end also, as regards the poor wash are the jets of the spray arms dirty or are the arms getting restricted.

She's not that old. Checked water end filter and it's good. All the jets are clear. It's a pretty fresh yoke. Got pushed up for a call out to the 27th from the 15th so will see what the pro says.

Thanks for the help. Been DIY rooting at the dishwashers for a lifetime and this one got me stumped. Maybe it's just a software problem

ok, what you need to do is as soon as the d/w stops pumping after switching on is open it and fill it with approx. 5 ltrs water, if it goes on to wash either the solenoid at tap end or main solenoid is open circuit, if you find both ok you need to find the feeding loom and disconnect at the joiner, it needs 230v on fill otherwise the pcb has a problem
