Re: Indesit DI620 – has 2inches of water in the bottom
The machine won’t do anything if the door lock has failed or the door is not correctly closing. You say the door is not closing rite so this would indicate the possible location of the fault.
A solid light means its still in cycle, You should be able to reset it by either holding the power or program button for 3 seconds. You should hear a series of beeps.
The simple fact is there are no easy things to check with a dishwasher. Specialist tools and knowledge are needed, years spent working on them helps.
Save your self time and hassle and call some one.
