Could a failing Door Latch / Door Switch Assembly cause the BOSCH DISHWASHER 500 SERIES WON T START to have symptom: Repair?

The red light flashing on the floor is a direct indicator that the appliance door is not completely closed or the control system believes it is not. This will prevent the wash cycle from initiating. Obstructions preventing the door from fully latching or a faulty door switch are common causes.

Could a failing Water Inlet Valve cause the BOSCH DISHWASHER 500 SERIES WON T START to have symptom: Repair?

The presence of water in the floor filter area, even after removal, suggests a leak into the base of the unit. A leaking water inlet valve is a frequent cause of water accumulation in the base, which can trip the flood switch (often associated with an E15 condition) and prevent the dishwasher from starting or powering on correctly.

Could a failing Excessive Sudsing / Detergent Residue cause the BOSCH DISHWASHER 500 SERIES WON T START to have symptom: Repair?

Over-sudsing from too much or incorrect detergent can lead to water overflowing into the base, triggering the flood switch and preventing the dishwasher from operating. While the water was removed, the underlying cause of the water accumulation needs to be addressed.

// ENGINEER'S LOG

The primary symptom of a flashing red light on the floor, with no error codes and the unit refusing to start, strongly points to an issue with the door latch or door switch, as the appliance manual indicates this light flashes when the door is not fully closed. Concurrently, the presence of water in the floor filter area suggests a leak into the base, which can also prevent the unit from running. This could be due to a faulty water inlet valve or excessive sudsing. It is critical to first ensure no physical obstructions are preventing the door from fully closing and latching. Simultaneously, investigate the source of the water in the base, checking for leaks from components like the inlet valve or assessing for signs of over-sudsing. // SAFETY NOTE: Ensure unit is disconnected from all power sources before inspection. Forensic analysis is for component identification only.
