Bosch washing machine beeps twice won't start
Model WAT28371GB/01 VarioPerfect EcoSilence Drive
The fill hose came off the soap dispenser causing a small water leak. So I removed both front panels and reattached the hose. Afterwards machine beeps twice and displays the door lock symbol. No error code displayed.
I've replaced both the door lock and the cable (from Bosch) but it still does the same thing.
The control panel seems OK. I can select any program and the correct times are displayed but soon as you press start you get the double beeps and the door lock symbol.
I've tried numerous different reset procedures found on the Web but Im not convinced I have found the right one for this machine. Vids suggest that the reset process should light up all the segments on the display but that never happens.
Anyone know the correct reset proceedure?
I'm an electronics engineer so know how to work safely on the machine.
Anything else to try?

Bosch WAT28371GB/01 beeps twice and shows door lock symbol after front panel removal
- The problem
- After a small leak from the fill hose at the soap dispenser was corrected and both front panels were removed/refitted, the washing machine would power up and allow programme selection, but pressing Start only produced two beeps and the door lock symbol. No fault code was displayed. Replacing the door lock and its cable did not change the fault.
- Likely cause
- Most strongly supported diagnosis is a door interlock activation problem caused by something disturbed during panel removal: either wiring/fixing around the door lock, or the door latch not operating the lock correctly. The accepted reply states a reset is not normally required for this type of fault.
- What fixed it
- Recheck the work carried out around the front panel area, especially the door lock mounting and associated wiring, and inspect the door latch for damage or poor spring action. The accepted advice also suggested applying a little WD-40 inside the door lock and on the door latch. The exact repair carried out was not confirmed in the discussion.
- Checks to try
- Confirmed no error code displayed
- Door lock replaced
- Door lock cable replaced
- Programmes and times display normally until Start is pressed
- Fault began only after front panels were removed and refitted
- Advised to inspect door latch condition and spring action
- Advised to recheck door lock wiring and fixing
- Parts or tools mentioned
- Door lock
- Door lock cable
- WD-40
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

It's remarkable how many people have replaced the door lock when suffering from this type of error and it didn't fix the fault. If it's not the door lock up fault it can only be wiring, or a problem with the door latch not activating the door lock properly. There shouldn't be any reset process necessary. With a washing machine, if there is a fault, then the washing machine will not work and all display an error code. As soon as the fault is fixed the washing machine works normally.
As this fault only occurred after removing the front panel the overwhelming suspect is that something went wrong during this process. So I would remove the panel again completely check all of the wiring and fixing of the door lock. I would also examine (probably first) the door latch. Is it okay not broken in any way, is it spring-loaded in one direction so that you can bend the latch against a spring and the spring then forces it back? Try spraying a little WD 40 inside the door lock and on the door latch.
