see this causes and fix it. God bless you
Door or Lid Latch Assembly If the washer lid won't lock the lid switch assembly might be defective. This is a very common problem. The lid switch assembly can fail either mechanically or electrically. Test any electrical switches with an Ohm meter for continuity. The switches should have continuity according to their design.

Door Lock Motor and Switch Assembly If the washer door won't lock the door lock assembly should be checked. The door lock can fail either mechanically or electrically. Test any switches on the door lock with an Ohm meter. The switches should have continuity according to their design.
Main Control Board If the washer door won't unlock the problem might be the main control board. This is not common. Normally the problem is with the lock mechanism.

Possible the surge would have made some changes in the main processor memory or damaged the processor. You can shut down the washer and remove the plug for few hours. press down all the panel buttons to drain all residual voltage on the board.
If the same fault repeats then it is possible there are errors on the board.

There's an auxiliary switch in the door lock.switch assembly that is activated at the end of the wash cycle for the machine to advance to the spin cycle. The machine will NEVER advance to the spin cycle unless the auxiliary switch is activated as a safety feature to prevent the door from opening during a high-speed spin cycle that may result in physical injury. The drum tumbles back and forth while the machine control checks the auxiliary if activated but since it's not, the control will not command the motor speed control to spin the drum at high speed. These symptoms may indicate a faulty door lock/switch assembly and may need replacement.

i think the problem from what you saying come from { a water level swith} because it contol also the door from opening when the water is still in the drum so it may need to change from the begining >
thanks

In some cases switching off and back on again solves it. Otherwise try to run Rinse & Spin cycle again, and if after cycle door will stay locked you'll need to check the door lock itself, its wiring and/or main PWB
Please Update me how is it going on this

you will need to remove the top cover and get a screwdriver to move the door latch over. it's a job for an engineer really as you have an electrical problem anyway.

i would get a new door or catch from the hotpoint website hope this helps

Try buttons "dry" & "spin" together for a few seconds. This is the child lock display.

Or press "end of cycle" for over 3 seconds.

Or press "options & select" till the light goes off.

Works for other machines..............And please rate me if helped

possible machine has not drained - this will prevent door opening.
put drain hose at floor level into a tray and drain that way then switch off at mains, wait 3 mins and see if door opens

It sound like a lid switch problem .A defective lid switch could prevent you to open the door physically and as well will not move to the unlock light.The switch located inside the machine near the door frame. You should open the top panel (open 2 screws and then slide it out) then you will have an access to it . You can test it by multi-meter (it is an on/off switch). In case of a deffective switch, it should be replaced. Be aware that you should remove machine's power cable before starting your test !!!! Good luck !!!
