Bosch SHPM78Z55N 24 in 500 Series Top Control 44 dBA E17 Error Fix: Over-Fill Level Exceeded

Error code E17 on the Bosch SHPM78Z55N 24 in 500 Series Top Control 44 dBA means: Over-Fill Level Exceeded. The water level in the wash tub has exceeded the maximum permitted level. This is a secondary overfill protection (E5 is the primary). The drain pump will activate to bring the water level down. If this code appears repeatedly, check the water inlet valve for a stuck-open condition. Verify the float switch is operating freely and not stuck by debris. Check the pressure sensor/switch and its air hose if equipped. Replace the inlet valve if water continues to enter the tub when it should be off.
