Symptom / Description

FAULT

Hotpoint ActiveCare & MaxiSpace 3D Zone Wash Dishwasher: Flow sensor open circuit error E7; control board detects broken circuit to water flowmeter reed switch board.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Hotpoint dishwashers: Corroded copper tracks or broken wire on 2-pin connector of the water matrix air break flowmeter PCB.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Inspect 2-pin wire harness between power board and flowmeter PCB. Check reed switch continuity while spinning turbine with magnet. Replace reed board. Press and hold Start/Cancel for 4 seconds until the active program cancels and completes drain cycle.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Isolate 230V mains power before accessing the lower pump housing.
!Prepare a shallow basin and absorption towels: expect 3 to 10 liters of stagnant trapped water upon filter opening.
!Beware of sharp foreign objects (broken glass, needles, screws) trapped inside the impeller cavity.

3. Preliminary Mechanical & Visual Checks

Unscrew coin trap filter and clear all foreign debris (coins, hairpins, bra underwires).
Rotate pump impeller manually: synchronous magnetic rotors should snap cleanly in 90° intervals without jamming.
Check drain hose for kinks, blockages, or unpunched sink spigots; verify drain height is between 65cm and 100cm.

Frequently Asked Questions: Hotpoint E7

FAQ TREE

What does error code E7 mean on a Hotpoint appliance?

Hotpoint error code E7 indicates: Hotpoint ActiveCare & MaxiSpace 3D Zone Wash Dishwasher: Flow sensor open circuit error E7; control board detects broken circuit to water flowmeter reed switch board..

What is the root cause of Hotpoint error code E7?

The primary root cause for Hotpoint code E7 is: On Hotpoint dishwashers: Corroded copper tracks or broken wire on 2-pin connector of the water matrix air break flowmeter PCB..

How do I fix or resolve Hotpoint error code E7?

To resolve error code E7: Inspect 2-pin wire harness between power board and flowmeter PCB. Check reed switch continuity while spinning turbine with magnet. Replace reed board. Press and hold Start/Cancel for 4 seconds until the active program cancels and completes drain cycle.

Is it safe to clear Hotpoint error code E7 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Hotpoint code E7 persists, the physical component causing On Hotpoint dishwashers: Corroded copper tracks or broken wire on 2-pin connector of the water matrix air break flowmeter PCB. must be inspected or replaced.

How do I test electrical resistance for Hotpoint code E7 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Drain Pump Motor Stator Coils across Across pump motor spade terminals (L-N unclipped). Expected nominal reading is 160Ω–220Ω (Sync 230V) / 20Ω–45Ω (3-Phase BLDC). Tolerance: ±10% balance. Insulation resistance between coil and motor chassis must exceed 20MΩ..

What safety protocol must be followed before servicing Hotpoint code E7?

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.
