How do I reset the leak prevention system safety valve on my AEG 86050?

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).

DISCONNECT FROM MAINS, REMOVE LOWER METAL COVER (EITHER FRONT OR BACK) WHICH IS HELD BY 2 STAR TYPE SCREWS, SPONGE OUT EXCESS WATER OR SOAK UP USING KITCHEN ROLL, FLOAT SWITCH LOWERS AND RESETS. PROBLEM SOLVED.

I solved the problem. removed metal plinth at bottom of machine (dacing front). You will nee a star screwdriver to do this. Make sure mains power is disconnected as you are now exposed!!
At bottom of the plastic tray you will pobavly notice it is full of water. (mine was). I simply used songe to saok up and squeeze out until known left. This uallows the float that sets off the leak system to reset. So long as you know cause nothing more to do. My machine now works perfectly. Occasionally leaking pipes will casue the lasrm to go off again. You will need to fix this as well if it does. Often the overflow is acsued by blockgae of filters inside that allows a spill-over.

I'd be interested to know. My wife had a serviceman in today who said it would be better to replace the machine!
