Hotpoint dc28 dishwasher prewash light flashing pump running even when empty

1.press cancel button
2.check if the door closes securely.
3.since there is water in d/w try running a short cycle.If it works, clean the inside thoroughly to ensure no clogs.

Flashing lights, pump running even when turned off. Had to switch off at the socket. The vibration from the machine had managed to give a quarter turn to the appliance gate valve, the type with the little blue handle. I could see the indentation in the rear rubber panel on the back of the dishwasher. Unscrewed the little blue handle, pushed the machine back in and started working as normal. :)

No solution! tried resetting to factory defaults but ended up that even the drain pump stopped working. after flooding the kitchen (nearly). I decided it was terminal and am loking for a new dishwasher urgently as I type. Cheers.

pump or heater

unplug it for an hour this normally fixes this problem on my machine

This is a blocked pump,Strip down pump and remove blockage.

power supply board may be defective.

standing water inside washer

check the base of the machine and see if it has water in it. if so, this will cause the dishwawsher to pump out all the time. mop out and it shoiuld run. you have a leak and will have to trace it - not always easy

I too had this problen today. Printed off a manual from the Hotpoint website. Very helpful troubleshoot section. Anyway, flashing eco and fast lights and beeping sound indicates 'water feed pipe blocked' You need to check the water inlet connections on your tap.However, when we pulled it out we noticed the blue water inlet pipe was slightly kinked. Straightened this out and hey presto! It works fine again. How this happens when its worked ok for 18 months will never know but still. Try it! hope this was helpful...shewoo
