How do I fix my Zanussi DCS 14w studio line dishwasher? It is constantly chugging and trying to drain water. I've put dishwasher cleaner in and tried vinegar but nothing works. It's even doing it when switched off (although the power at the plug is still switched on). Any amount of water I put in it is always drained away but it keeps tyring to drain without any water there. The only way to stop it is to switch it off at the mains, and it starts up again as soon as the mains is back on.

this model has a sealed base which is full of water due to a leak, this operates a float

switch that disables machine but brings pump on.this model does have an aquastop float

switch. it could have been activated by foaming. this is usully caused by cheap detergent

or by fairy liquid contamination. as it is a bench top model i'd suggest that you unplug

it and gently tilt it backwards on the draining board. you will probabably get a couple of

pints of water running out. once it stops give it a go. if there is no permanent cause

then you're up and running. however it may stop again so the the cause will have to be

found. if no water runs out then it may be due to the anti syphon valve which is fitted

internally in line of the drain hose. there is a modified part which replaces the older

version which was prone to air locks. the new part has a red nut and is part number

150957501/3. the older version has a white nut. these valves are found behind the side

panel.
