Kermi Appliance Repair in Duryard and St James

What does Error 4 mean on a Kermi x-change fresh heat pump?

Error 4 indicates that the temperature sensor on the evaporator connection is interrupted. LED 3 shows red and the compressor will shut down. Check the sensor cable connection and contact a technician to replace the sensor if necessary.

What does the Al001 error mean on a Kermi x-change dynamic heat pump?

The Al001 error indicates a general error at the frequency converter (Power+ LED flashes red). This can occur due to communication issues between the frequency converter and refrigeration circuit controller. Perform a manual error reset, verify voltage and phase sequence, and check the compressor current draw. If the issue persists, contact a qualified heat pump technician.

What does the Al039 error mean on a Kermi x-change dynamic heat pump?

The Al039 error indicates a phase error detected at the motor connection. This requires professional repair. Contact a qualified technician to verify electrical connections and motor wiring.

What does the Al026 error mean on a Kermi x-change dynamic heat pump?

The Al026 error indicates that the frequency converter has detected insufficient power supply. Check the electrical supply voltage. Perform a manual error reset. Contact a technician to verify Power+ connections.

What does the Al019 error mean on a Kermi x-change dynamic heat pump?

The Al019 error indicates that the electronic expansion valve actuator reports a failure. The expansion valve motor or its wiring may be defective. This error requires professional repair. Contact a qualified technician to inspect the expansion valve actuator and wiring.

Use Kermi's specialist partner search tool to locate qualified installers in your area. Authorised specialist partners provide professional advice, careful planning, and expert installation.

What is hydraulic balancing and why is it important?

Hydraulic balancing ensures each radiator receives precisely the amount of heating water needed for efficient, even heating throughout your home. Without proper balancing, radiators near the pump may receive too much water while those further away receive too little, causing uneven heating and wasted energy.

What is Kermi therm-x2 technology?

Therm-x2 is a patented technology that uses serial flow through multi-layer flat steel panel radiators. The front panel heats first, then rear panels activate as demand increases. This results in heating periods that are up to 25% shorter and enables energy savings of up to 11%.

Which Kermi radiators are suitable for low flow temperatures?

Modern radiators with larger surface areas work efficiently at low temperatures typical of heat pumps. Specialised heat pump radiators like the x-flair, with integrated fans, significantly improve heat distribution and convection at these temperatures.

Can I replace a standard radiator with an x-flair heat pump radiator myself?

The physical replacement is straightforward as lug positions are identical to standard radiators, allowing existing brackets to be reused in most cases. However, the x-flair requires an electrical connection for its integrated fans, which should be installed by a qualified electrician.
