Could a failing Drain Pump cause the BOSCH SHP865ZD5N to have symptom: Water In Bottom?

The drain pump's synchronous motor relies on specific magnetic timing to rotate the impeller; physical obstructions or internal winding degradation prevent the evacuation of water. If the pump cannot overcome the head pressure of the drain hose, water remains in the sump at the end of the cycle. Replacing the pump restores the mechanical force required to purge the system.

Could a failing Non-Return Valve (Check Valve) cause the BOSCH SHP865ZD5N to have symptom: Water In Bottom?

This valve is a one-way flap located near the drain pump that prevents dirty water from flowing back into the dishwasher after the pump stops. If the flap is stuck open by debris or has warped due to thermal fatigue, the volume of water stored in the vertical rise of the drain hose will drain back into the tub via gravity. This part ensures the fluid dynamics remain unidirectional.

Could a failing Water Inlet Valve cause the BOSCH SHP865ZD5N to have symptom: Water In Bottom?

If water appears in the bottom while the dishwasher is not in use, the inlet valve's internal diaphragm has likely failed to create a watertight seal. Micro-sediment or spring fatigue within the solenoid housing allows a constant, low-flow bypass of water from the main supply line. A new valve restores the electromechanical gate necessary to hold back line pressure.

What is the most likely root cause for a BOSCH SHP865ZD5N with symptom: Water In Bottom?
