My Bosch front end washing machine will not start a cycle. Door is closed tightly and when I push start/pause red light comes on & immediately goes off-this happens every time I push the start/pause button. I have tried unplugging the maching for 15+min., and restarting. All other displays light up properly and there is no error message.

"Sd" - (Excess suds)
F8 followed by E1 - (water supply error)
F9 followed by E1 - (drain pump system error)
F5 followed by E2 - (door will not lock)
F7 followed by E1 - (motor drive error)
"rL" - (remove load)
Washer making error beeps - Door has not been opened and closed for at least 3 cycles
Washer beeps when HOLD TO START is touched - Door not closed
F# E# code other than as described above appears in display - System Code Error
"nt" (interrupted) - Cycle was paused or cancelled
Clean Washer LED flashing at end of wash cycle - The washer has run 30 wash cycles and is indicating a reminder to run the Clean Washer cycle https://removeandreplace.com/2015/05/05/washing-machine-error-codes-front-and-top-load

Make sure the machine is able to fill. Check the taps are on. Check the machine on a spin only cycle. If it works , great, if not, it could be a dud door switch. Does the door actually lock when the "lock" light comes on?

It sounds like a door switch fault see if the end light and the start/pause light are flashing count the flashes if end flashes 4 times and the start/pause once or maybe more this could be error 41, door switch fault.A door switch would cost about $ 20 but there may still be a problem with the main Programmer.
Good luck.

Child lock active.
Hold start button 10 seconds.
Then it will deactivate.

If this is not the case, door lock fault or main board fault.
