Hotpoint dishwasher mod BFV620W starts then pumps out water,and the second and forth lights on control panel flash non stop

It sounds like there may be a problem with your Ariston dishwasher. The flashing lights and the dishwasher's inability to wash could be caused by a number of issues, including a problem with the control panel, a faulty water inlet valve, or a clogged wash pump.
To troubleshoot the issue, you can try the following steps:

1. Check the control panel for any loose or damaged wires. If you find any loose or damaged wires, try to secure them or repair them as needed.
2. Check the water inlet valve to make sure it is not clogged or faulty. The water inlet valve controls the flow of water into the dishwasher. If it is clogged or faulty, it could cause the dishwasher to stop working.
3. Check the wash pump for any blockages. The wash pump is responsible for circulating the water during the wash cycle. If it is clogged, it could prevent the dishwasher from washing properly.

Possible that the inlet valve, inlet filter is clogged and so there is low pressure or flow of water into the washer. Secondly the water level sensor can be faulty and so since there is no detection the processor is shut down..

I had the problem of flashing lights and water did not pump out.Found a piece of bacon in drain pump wedged between impellor and pump body...cleaned it out...problem solved..

I had same symptoms on a Hotpoint dishwasher.
Turned out to be a failed water heater.
The logic in this case goes like this:
When wash cycle starts, the first thing the machine does is pump out any water that has collected in the sump since it was last run.
It then allows a small amount of clean water in and enables the water heater.
If heater okay, it then continues with the rest of cycle.
In this case, the control board detected failed heater so pumps out the water and then stops with an error code shown by a flashing lamp.

No simple fix I'm afraid - machine had to be turned on its side, bottom panel removed, several items had to be removed to get at the water heater which was then repalced with a new one.

You dont state what make/model your dishwasher is so maybe worth adding this information as someone else may recognise your fault and have a quick fix.

ive not worked on hotpoint dishwashers,does the dishwasher drain? at the point it plays up is it supposed to be filling or washing.check the filters inlet valve etc.do you still have the manual for the dishwasher.the flashing lights are most likley a fault code but we dont get hotpoint dishwashers in australia.sorry i cant be of more help.Ian

food stuck in drain pump remove and clean out or scoop out - soak up all water then fill with 3 or 4 hot litres of water . cancel programme , start new one ( first thing unit does is switch to drain cycle ).
Then rock machine back and forth - this sometimes frees jammed debris thus pumping out of machine.
This works for me i have done it several times and it works
