Why Kermi Appliances Need Specialist Repair
Kermi appliances incorporate advanced proprietary systems that require certified engineers with brand-specific training to diagnose and repair correctly.
Kermi appliances use integrated electronic diagnostics. Our engineers connect directly to Kermi control boards using brand-specific tools to read fault codes and pinpoint issues accurately.
Every repair uses genuine Kermi spare parts sourced directly from authorised distributors. Original components ensure compatibility, performance and longevity — backed by a manufacturer warranty.
Kermi appliances must meet strict UK safety regulations. Our certified engineers follow Kermi service procedures and test every repair to BS EN standards before sign-off.
Many Kermi appliances feature Wi-Fi connectivity and smart home integration. Our engineers can diagnose firmware issues, reset connectivity modules and restore remote control functionality.
Common Kermi Error Codes
What does the Al016 error mean on a Kermi x-change dynamic heat pump?
The Al016 error indicates that the minimum allowable superheat threshold has been exceeded, suggesting issues with the refrigerant cycle. Perform a manual error reset. This error requires professional diagnosis. Contact a qualified refrigeration technician to inspect the expansion valve and verify refrigerant levels.
What does the Al020 error mean on a Kermi x-change dynamic heat pump?
The Al020 error indicates that the minimum allowable suction temperature threshold has been exceeded. If ice is visible on the evaporator, carefully remove it. Perform a manual error reset. Contact a technician to inspect the refrigerant levels and sensor calibration.
What does the Al049 error mean on a Kermi x-change dynamic heat pump?
The Al049 error indicates that the maximum permissible discharge temperature has been exceeded. Check that all hydraulic valves are open. Clean the water filter. Bleed air from the primary circuit. Contact a technician to inspect the expansion valve and refrigerant levels.
What does the Al018 error mean on a Kermi x-change dynamic heat pump?
The Al018 error indicates that the maximum allowable evaporation temperature threshold has been exceeded. Verify the outdoor unit fan is operating correctly. Perform a manual error reset. Contact a technician to check expansion valve settings and functionality.
What does the Al033 error mean on a Kermi x-change dynamic heat pump?
The Al033 error indicates that settings parameters have been reset to defaults. The system configuration may have been lost unexpectedly. Perform a manual error reset. Contact a technician to reconfigure the system parameters.
Frequently Asked Questions
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%.
What is ventilation with heat recovery?
Ventilation with heat recovery transfers heat from extracted stale air to incoming fresh air without the airflows mixing. This preheats the supply air, significantly reducing heating energy requirements. Depending on the system, around 90% of heat can be recovered.
How long are Kermi shower enclosure spare parts available?
Kermi offers a 20-year after-sales guarantee for spare parts, even after the model has been discontinued. The product data on the back of the instructions or the ID code on the shower enclosure makes it easy to identify and purchase replacement parts.
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 Kermi radiators work with heat pumps?
Yes, this is possible without any problems. Modern heat pump radiators like the Kermi x-flair are specifically designed for efficient operation at the lower temperatures typical of heat pump systems.
