Hotpoint BFI 620 problem

[fixitplease48]

A couple of days ago, our Hotpoint BFI 620 starts by flushing out the water as usual, fills up with water and then works for about 2 mins, pumps out the water and stops without running the full cycle.
When door is opened, it has two of the four lights on the left top little screen flashing.
What do I need to do to get this fixed?
Thanks

You can start by telling me which 2 lights flash out of the 4. Or 1 and 3 or 2 and 4 etc.

Lights 2 & 4.

Thanks for the diagnosis.
Shame this dish washer was not designed to carry on working after heater failure, even though the wash would not be brilliant in cold water.
Best wishes.
