Bosch Dishwasher Symptoms — Complete Troubleshooting Guide

Twenty-two Bosch dishwasher symptoms on the SHX, SHP and SHV platforms, and most of them end up at an E-code. E15 is the AquaStop leak float tripping, E09 the flow-through heater, E24 and E25 the drain path, E17 an overfill. On models without a display the LEDs blink that same code out, so the blink count is read rather than counted. A tab still sealed at the end of a cycle is the bi-metallic dispenser door, not the detergent.

Two habits make this hub fast. Read the code before touching anything, and note the minute the cycle stopped at — an early stop is usually AquaStop or the door switch, a mid-wash stop is the heater. The drying guide is the one to read before assuming a fault at all: most of these machines have no heating element and dry by condensation, so rinse aid and unloading order decide the result.

The boundary sits at the heater and the base. A flow-through heater shorting to ground is what trips the breaker, and it is wired into the sump under the tub; the AquaStop valve is on the supply hose at the tap end. Cleaning the filter, freeing a spray arm, levelling the machine and clearing an E15 float are homeowner work. Once the diagnosis reaches the heater, the pump or the board, book the repair.
