Dishwasher not draining - Hotpoint LST216A

Dishwasher not draining - Hotpoint LST216A Hi until today I had not used my dishwasher for nearly a year. It was working when I last used it. However today when I ran a wash, it fills up fine but after a while stops running and just shows specific lights flashing. The water does not drain and it remains at the bottom.

"Hi,

Are all 3 lights flashing or just the Eco and Normal cycle lights with the Power light on steady?

Research online seems to indicate that for your model if the Eco light and the Normal light are flashing it is a heating problem

Can you stop the dishwasher after it has filled and started to wash (opening the door usually stops a dishwasher) to check if the water is hot or not.

If it is not hot then you may have to first check if the heater element is OK .

Hi,

Apologies.

I was just going off the control panel for a LST216 from the user manual, but maybe the LST216A is different.

Does your control panel look like this and are the indicated lights the ones that are flashing?

Just curious. Are the dishes on the top rack getting wet? Can you check if the spray arms are turning?

Align them in position front to back or side to side and run the machine. Stop after it begins to wash and check if they have moved."

I think the issue could be with the pump is stuck or tubing within the machine is clogged and is not letting the pump work. Since the machine was inactive for so long, lime and other minerals might have got the pump stuck. If you can get to it, try hitting it gently with a small hammer while it’s trying to drain. This might be the source of the humming and may loosen up the blades. I would also suggest pouring some industrial anti lime solution without cloths inside the machine.
