    What to do if KWB Multifire USV 80/100 D/ZI Heating System fuel extractor motor is overloaded?
    • J
      Jane LynchAug 12, 2025
      If the motor of the supplemental fuel extractor is overloaded, it could be due to foreign objects in the fuel. Open the overfill protection cover on the worm trough and remove any foreign objects. Alternatively, the wood chips may be too large or too fine. Use standardized wood chips (G30 = max. piece length approximately 30 mm). A failed mains phase could also be the cause, so check the power supply.

    What to do if the fuel extractor module supply is interrupted in KWB Multifire USV 80/100 D/ZI?

      If the supply to the fuel extractor module is interrupted, first check the CEE plug-in connector to ensure the fuel extractor module is properly plugged in. If the issue persists, it could be due to one or more tripped glass-tube fuses, a connector malfunction in the three-phase current module, or a missing/short-circuited 24-volt supply voltage. In such cases, notify customer service.

    What to do if the overfill protection switch of the KWB Multifire USV 80/100 D/ZI fuel extractor is overloaded?

      If the overfill protection switch of the fuel extractor is overloaded, switch off the main switch and switch it on again to open the fire shutter. Then, open the overfill protection cover and remove all the wood chips in this area. This issue typically arises when the shaft is clogged, preventing the worm from getting stuck.

      Cynthia JamesAug 31, 2025
      If the Power-LED is OFF, check the line voltage to the module (3P+N+PE) and inspect the glass-tube fuses in the module. If those are fine, the module might be defective and may need replacement.

      Jeanette PonceSep 4, 2025
      If the BUS-LED is OFF, check the line voltage to the module (also on the boiler), inspect the bus cabling, and verify the station number (position 1). Also, check the hardware settings on the boiler control unit. If none of these steps resolve the issue, the module might be defective and require replacement.
