H-Koenig LDS-11

Q: What does error code LDS-11 mean on a H.Koenig appliance?

H.Koenig error code LDS-11 indicates: H.Koenig SWRC90 / SWRC110 / WaterMop Laser LDS Smart Robotic Vacuum & Mop: Diagnostic fault code LDS-11 registered by the microcomputer controller. Lithium-ion battery pack pack cell voltage critically depleted (< 12.0V DC).

Q: What is the root cause of H.Koenig error code LDS-11?

The primary root cause for H.Koenig code LDS-11 is: On H.Koenig appliances engineered with 360° laser LDS distance turret (5-8 Hz), twin DC wheel drive motors with encoders, 20W BLDC suction fan, and 14.8V 2600mAh lithium battery with thermal cut-off: robot stranded off dock for days or internal 18650 cell imbalance BMS cutoff Metrological tolerance verification: battery pack nominal 14.4V-14.8V (4S 18650); BMS shutoff triggers below 11.2V DC..

Q: How do I fix or resolve H.Koenig error code LDS-11?

To resolve error code LDS-11: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: place robot manually onto charging base; verify charging current (> 1.0A); replace battery. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: turn off the mechanical master rocker switch under the chassis, clean optical cliff sensors and wheel hubs, place robot on charging dock, and hold Auto for 5 seconds.

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.
