Bosch dishwasher whining

Unplug it then plug again in 5 minutes. It should set it up to factory settings

Assuming you have verified water is actually getting to water valve, most likely water valve is the problem and needs replacing.

This may sound odd but might work.

Reset the machine as to start a new cycle. Add 2-4 cups of water. If the machine starts and runs through a cycle then the water inlet valve needs to be replaced.

Good luck

You seem to have inadvertently put it into the test sequence. Try pressing the two reset button simultaneously (usually the reset buttons are 1st and 3rd from left each with a dot underneath, if this does not work, press the button between the two resets (2nd button) P1 should come on then press the right reset button. The unit should run through a test cycle for approx 20mins and eventually reset the module, this is indicated by 0 in the display. Please repost if further assistance required.

You should be able to get several more years out of it with a good maintenance call or a Do It Yourself routine on checking your water inlet valve. spray arms, internal filters.

yes the problem from the heater.

if the sound coming from boiler heater means
1)scaling on the boiler tank(tank to be cleaned).
2)check any loose connection on the heater wire.

I have a Bosch Dishwasher and the E-Nr is SGS4362EU/03. The machine is approximately 4 years old, in good condition and has been working very well. Suddenly, there is water remaining after it completes a 50 degrees C wash cycle. This is also evident with the pre wash cycle and the 65 degrees wash cycle.

I have checked and cleaned the filters. I have loosened the internal pump white cover (Torx T 20 screw) and checked for any physical blockage - none. I have also checked for any drainage hose kinks - none.

I have tried a series of empty washes and the machine drains the water during the wash cycles. The dishes are also have a dull colour and show show signs of not being properly rinsed during the wash cycle.

Please assist.

It is possible that some of the pips have been washed down into the drain pump and jammed the impellor, follow the drain hose back to the pump underneath of the dishwasher make sure the d/washer is switched off at the power supply before you attempt this, if you have reasonable mechanical skill you should be able to remove front of pump to clean it.

your main wash motor is faulty it must be replaced.

It could be the impeller on the motor. The impeller fits over the shaft of the motor and might have split/broken up. That funny noise is probably the shaft spinning inside the damage impeller. Fortunately the impeler is fairly inexpensive and easy to replace. I believe there are one or two parts/covers to remove that are held in by a roughly half dozen torx screws.
