We have a fairly new (under 2 years) Hotpoint HIC 3B19 C UK Dishwasher.
It has been running fine up until now but yesterday my wife opened the door mid cycle to put in something she had forgotten and after closing the door it would no longer run.
There are no error messages. The lights come on as normal after pressing the standby button, the program selection works fine, the start/pause button flashes as normal until we press it which makes it go solid. We then close the door.
At this point there used to be a single long beep and the cycle would begin but this no longer happening and instead after a few seconds we get 3 beeps and we are back to the previous stage with the play button flashing.
This behaviour is identical whether we close the door or not. (ie 3 beeps goes back to flashing play button)
Can anyone please shed any light on how to diagnose or fix the problem. I am good with working with systems, internal components and circuitry so please don’t hold back on any technical discussion.
Thanks
Robert
I’m not sure, how would I best verify this? Are these switches easily accessible? Would a valid way forward be to hard wire the switch to see if the cycle starts? Or is there any easier way to test?
does the door feel like its latching the last inch. can you feel the click as it closes
get a lot of units where the lock is in the closed position even though the door is open. result no start
lock is inside the door at the top
Dave
It is making a satisfactory click when the door closes. Although the mechanism is working, I’m wondering if the switch might still be faulty?
you would hope a new switch was not faulty
have you checked its not got a child lock and its on by accident ?this is where if you had bought a Beko or Bosch it would still be guaranteed
Dave
Yes I wish it was still under warranty.
I’ve checked the instruction manual and I don’t see a child lock feature or anything on the control panel indicating that one is active.
There isn’t much documentation with this model, I can’t seem to find any sort of service manual online ?
I’ve opened the top panel and removed and tested the door switch and the mechanism works fine and a continuity test with a multimeter shows that the 2 contacts connect when the mechanism is in the shut position. So that rules out the door switch being the problem.
I am now considering how to proceed. Is there a further simple test that is worth trying to reach a diagnosis?
If not I am considering calling in an engineer, Is it better to arrange via hotpoint helpline or is it better to call an independent engineer?
If anyone knows a good dishwasher engineer in the North London area please recommend.
Thanks
Robert
well you could look here for an engineer

but if it is a board problem unless the independant can programme boards its a Hotpoint only job
also i think it would be covered byextended part guarentees from hotpoint so hopefully any parts are free. just pay for labour
they sometimes let you take out an insurance plan and do the repair and then its covered ongoing.

Booked an official engineer. Fixed in 20 minutes. He started by changing the door switch but it wasn’t that. He changed the wiring loom that connects the door switch to the circuit board… all fixed!
It appears the opening and closing of the door resulted in a break in a wire stopping the door switch from telling the circuit board that the door was closed and therefore starting the cycle.
its not so much the loom its the routing
bad design
most looms that go horizontal for 75mm or so at the door hinge are less likely to give problems
the ones that go straight through are bending in the same place and so snap after so many uses
