Bauknecht GSX4756 dishwasher

I think.
However, rarely have I encountered an inlet valve that emitted a burning smell. So I'd expect there to be some other problem in there.
But, if the inlet valve didn't pass the test, then it needs to be replaced. Plus, if it was stuck on the rinse cycle and the valve was out, then that is where the cycle would hang up.
Burning smells usually come from a motor, a belt, shorted wiring or a heating element. So if everything else checks out, then go for replacing the valve. The instructions are included in our dishwasher repair section.

The timer is not advancing to the next cycle. Replace the timer.

Need a new timer.

Bauknecht are built by Whirlpool.
F7 on Whirlpool means flow meter failure.
Check water inlet, check the pressure switch, and check the sump filter at the bottom of the dishwasher.
To reset try turning on the power and holding the start button and the + and - buttons at the same time.

Set the machine to the end of the drying cycle, when it has finished, try pouring boiling water into the machine about a kettle full there is a sump level control beneath the removable filter (where all the **** gathers) if this has fat deposits on it this type of problem can occur.

have got a bauknecht gsx4756 which when started beeps continually and start light flashes. it automaticaly then flashes the rinse button as well. I have reset holding down start and mode selection button next to the start button the fault keeps recurring. just wanting to know what the problem is before paying an engineers extortionate call out fees

You need to reset the computer on the bottom. Had the same problem with mine. The Blinking led means the heating element is bad and will not operate.

The F7 means that the drain filter is blocked or your water pressure is low. Check and clean filters. Good luck !
