What does error code EA 227 mean on a Worcester Bosch boiler?

Error code EA 227 on a Worcester Bosch boiler means no flame detected or flame signal lost during operation. The boiler has detected that the flame has gone out unexpectedly. Do not attempt to repair gas appliances yourself. Check that other gas appliances in your home are working to confirm gas supply. If you smell gas, do not operate any electrical switches, ventilate if safe, leave the property immediately and call the gas emergency line from outside. If there is no gas smell, contact a Gas Safe registered engineer for professional diagnosis.

What does error code FA 364 mean on a Worcester Bosch boiler?

Error code FA 364 on a Worcester Bosch boiler indicates the gas valve EV2 leak test has failed. This is a critical safety fault indicating a potential gas leak from the valve. Do not use the boiler under any circumstances. If you smell gas, do not operate any electrical switches, ventilate if it is safe to do so, leave the property immediately and call the gas emergency line from outside. Contact a Gas Safe registered engineer immediately. Do not attempt to reset or operate the boiler until it has been inspected and repaired.

What does error code 9U 233 mean on a Worcester Bosch boiler?

Error code 9U 233 on a Worcester Bosch boiler indicates a problem with the code plug or heat control module (HCM). The code plug may be faulty or not connected properly, or the control box may be defective. Do not attempt to access internal components. Contact a Gas Safe registered engineer for professional diagnosis as control module faults require specialist equipment.

What does error code EA 229 or D5 mean on a Worcester Bosch boiler?

Error code EA 229 or D5 on a Worcester Bosch boiler indicates a frozen condensate pipe or loss of ionisation signal. The condensate pipe drains water waste from the boiler to an external drain and can freeze during cold weather. In winter, locate the condensate pipe (small white or grey plastic pipe on the exterior) and pour warm (not boiling) water over the frozen section to thaw it. Do not attempt any repairs involving gas components. If thawing does not resolve the issue, or if you smell gas, do not operate any electrical switches, leave the property and contact a Gas Safe registered engineer from outside.

What does error code C4 273 mean on a Worcester Bosch boiler?

Error code C4 273 on a Worcester Bosch boiler indicates the fan has failed to stop or airflow is still present when it should not be. This suggests a fault with the fan motor, speed sensor, or control board. Do not operate the boiler with this fault as it affects combustion safety. Do not attempt any repairs yourself. Contact a Gas Safe registered engineer immediately.

Do I need a cylinder with a Worcester Bosch heat pump?

Yes, Worcester Bosch heat pumps require a hot water cylinder as they do not provide instant hot water like a combi boiler. The Greenstore range of cylinders is designed specifically to work efficiently with Worcester Bosch heat pumps.

How often should I service my Worcester Bosch heat pump?

Worcester Bosch recommend having your heat pump serviced annually by a qualified engineer with appropriate certification for heat pump systems. Regular servicing ensures optimal efficiency, extends the lifespan of the unit, and maintains your warranty coverage.

How does a Worcester Bosch heat pump work?

A Worcester Bosch heat pump works similarly to a refrigerator in reverse. A water and glycol mixture circulates through the collector circuit, causing refrigerant in the evaporator to transform into gas. This gaseous refrigerant passes through a compressor, which significantly raises its temperature. The heated gas then moves to the condenser, where it releases its energy into the heating circuit. This thermodynamic cycle efficiently transfers thermal energy for home heating.

What is the lifespan of a Worcester Bosch heat pump?

Worcester Bosch heat pumps have an expected lifespan of 20 years or more with proper maintenance and annual servicing. This is typically longer than a traditional gas boiler.

How long does a Worcester Bosch cylinder take to heat up?

A Worcester Bosch Greenstore cylinder typically takes 20 to 45 minutes to heat from cold, depending on the cylinder size, boiler output, and incoming water temperature. Larger cylinders and heat pump installations may take longer.
