H-Koenig ICE-01

H-Koenig error code ICE-01 indicates: H.Koenig KB12 / KB14 / KB15 / KB20 Fast Automatic Ice Cube Maker Machine: Diagnostic fault code ICE-01 registered by the microcomputer controller. Water shortage in lower reservoir; magnetic float switch not raised.

The primary root cause for H-Koenig code ICE-01 is: On H.Koenig appliances engineered with R600a compressor ice-making module, copper nickel-plated evaporator finger grid, 12V DC water circulation pump, synchronous ice pusher motor, and infrared bin sensors: reservoir empty, water level sensor float stuck on scale, or micro-pump filter clogged Metrological tolerance verification: magnetic reed switch resistance < 0.5 Ω with water filled; open circuit when dry..

To resolve error code ICE-01: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: refill reservoir with potable water; free float on post; clean pump intake strainer. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: unplug the power cord for 2 minutes, empty water basin completely using drain plug beneath, refill with fresh cold water to Max mark, and hold Power for 5 seconds.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if H-Koenig code ICE-01 persists, the physical component causing On H.Koenig appliances engineered with R600a compressor ice-making module, copper nickel-plated evaporator finger grid, 12V DC water circulation pump, synchronous ice pusher motor, and infrared bin sensors: reservoir empty, water level sensor float stuck on scale, or micro-pump filter clogged Metrological tolerance verification: magnetic reed switch resistance < 0.5 Ω with water filled; open circuit when dry. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Compressor Motor Windings (Run/Start) & Defrost Heater across Across 3 compressor pins (Common, Run, Start): R(C-S) + R(C-R) = R(S-R). Winding to earth: >20MΩ (OL).. Expected nominal reading is 15Ω–25Ω (Run C-R), 20Ω–35Ω (Start C-S), 200Ω–400Ω (Defrost Heater). PTC Relay: 10Ω–30Ω at 25°C.. Tolerance: ±10%. Any low insulation resistance to casing (<2MΩ) trips the breaker. Defrost bimetal reads <0.5Ω when sub-zero..

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.
