Franke E7

Q: What does error code E7 mean on a Franke appliance?

Franke error code E7 indicates: Franke Mythos FDW / Maris Active Kitchen Integrated Dishwasher: Diagnostic fault code E7 registered by the microcomputer controller. Optical turbidity sensor measurement out of calibration / dirty lens.

Q: How do I fix or resolve Franke error code E7?

To resolve error code E7: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: clean turbidity sensor optic lens in sump and check 5V DC supply. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Press and hold Start/Pause for 5 seconds until the display shows '0:01' or cancels the cycle. Close the door to allow 60 seconds of drain down, then switch off power for 30 seconds before restarting.

Q: Is it safe to clear Franke error code E7 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Franke code E7 persists, the physical component causing On Franke appliances engineered with Dynamic Flow hydraulic wash circuit with BLDC variable-speed circulation wash pump, optical dual turbidity sensor, and active condensation drying turbine: infrared lens coated with detergent film Metrological tolerance verification: clean rinse voltage > 4.2V DC; dirty < 1.5V DC.. must be inspected or replaced.

Q: How do I test electrical resistance for Franke 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..

Q: What safety protocol must be followed before servicing Franke 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.

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.
