Disconnect at mains and turn off water supply (at start of inlet hose). Pull dishwasher out (if it's built in it may have a couple of screws securing it to the worktop or cupboard sides, locate these undo and then pull out dishwasher) taking care not to damage or over pull the water and outlet hoses.
Rear of dishwasher has a curved back plate near bottom of machine. Use Allen key to undo the two Allen bolts (one on each side) Remove backplate. If you look in the rear at centre of machine you will see a small square polystyene "float"(This floats on any leaked water and actuates a micro switch which triggers the alarm and pump). Use kitchen roll or rags to mop out the water. Reassembly is reverse of above procedure. Turn on water tap at inlet and reconnect electrical supply to dishwasher. This should solve the problem. It is a good idea to clean out the filters (when you remove it. This is in three parts:- outer fine mesh, metal middle filter and inner plastic one:-- all pull apart and fit back together easily) in the centre at the bottom of the main dishwash compartment. Dismantle and run hot water through them. Reassemble and put back in base of dishwasher. Also use a dishwasher cleaner to run through full cycle to remove grease from outlet hose. The above repair should work as the automatic leak switch operates if there is water present. Usually caused by blockage or partial blockage of filters/outlet hose. If there is a faulty hose in the base of the unit then the alarm will sound again once you try to use it after doing the above. If so....it's time to get an engineer! Note, The above has worked twice for me. If you are unsure of working on any electrical appliance then get a qualifed engineer.I offer the above opinion based on my personal experiences only and will not be held liable for any injury or damage to persons or property.(see this Website Terms and Conditions also).
