Hotpoint F8

Hotpoint error code F8 indicates: Hotpoint ActiveCare & MaxiSpace 3D Zone Wash Dishwasher: Sump water level inconsistency or diverter fault F8; OWI sensor optical reading conflicts with pressure calculation..

The primary root cause for Hotpoint code F8 is: On Hotpoint dishwashers: Fat or grease film coating the optical sensor lens, heavy detergent foaming, or motorized diverter valve (MDV) stuck mid-position..

To resolve error code F8: Clean optical OWI sensor face in sump bottom with warm soapy water and soft sponge. Verify diverter motor resistance (6.0–7.5 kΩ). Recalibrate optical sensor. Press and hold Start/Cancel for 4 seconds until the active program cancels and completes drain cycle.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Hotpoint code F8 persists, the physical component causing On Hotpoint dishwashers: Fat or grease film coating the optical sensor lens, heavy detergent foaming, or motorized diverter valve (MDV) stuck mid-position. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Mechanical Pressure Switch Contacts / Inductive Frequency Sensor across Across switch spade contacts with harness unplugged; electronic output: 40Hz–50Hz frequency signal. Expected nominal reading is Mechanical: Continuity 0.0Ω–0.2Ω (Empty: 11-12, Full: 11-14). Electronic: 20Ω–45Ω coil resistance.. Tolerance: Mechanical switch contacts must transition cleanly on gentle breath pressure. Coil ~22Ω ±5%..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
