What to do if my Schwank Heater shows error code 1 (ionization error during start)?
- J
  Jesse WoodsAug 9, 2025
  If your Schwank Heater displays error code 1, indicating an ionization error during start, it could be due to several reasons. First, check the gas line to ensure it is properly vented and that the gas cock is open. Other potential causes include a faulty gas valve (which would need replacement), damaged or dirty ignition and ionization electrodes (inspect, clean, or replace them), an incorrect gas throttling screw setting (adjust it accordingly), or poor grounding (ensure proper grounding of the system).

What causes Schwank calorSchwank D 40 U Heater error code 10 (MODBUS signal missing error) and how to fix it?
- D
  Donna CannonAug 15, 2025
  Error code 10 on your Schwank Heater indicates a missing MODBUS signal. This can occur due to an interruption in the MODBUS connection lasting longer than 3 minutes, in which case you should restore the MODBUS connection. Alternatively, it may be caused by incorrect wiring between the IC4000/1 and the SchwankControl Touch; ensure that the wiring is correctly configured.

Why does my Schwank calorSchwank D 40 U Heater show error code 2 (ionization error during operation)?
- V
  Vicki CarterAug 21, 2025
  Schwank Heater error code 2, which indicates an ionization error during operation, can be attributed to a poor low ionization current (less than 0.7?A DC). In this case, increase the ionization current. Another possible cause is too low connection pressure, so check and adjust the connection pressure accordingly.

What to do if my Schwank calorSchwank D 40 U Heater displays error code 5 (encoder signal missing error)?
- R
  rodriguezmalloryAug 27, 2025
  If your Schwank Heater is showing error code 5, which means the encoder signal is missing, it could be because the PWM fan isn’t running due to issues like a broken impeller or motor. Try to repair or replace the PWM fan. Another possible reason is a broken PWM cable, which would need to be replaced.

How to fix Schwank calorSchwank D 40 U Heater error code 9 (wrong setting fan speed parameters)?
- C
  Christopher LewisSep 2, 2025
  Schwank Heater error code 9 signals that the fan speed parameters are set incorrectly. This could be due to wrong settings for the fan speed parameters [PP04, PP05, PP06], so adjust the fan speed parameters accordingly. It may also indicate a damaged fan, such as bearing failure, in which case you should replace the damaged fan.
