Worcester Bosch recommend that water softeners can be used to prevent scaling in the hot water circuit, but the central heating circuit should be filled with hard water and a chemical inhibitor instead.

Should I turn my Worcester Bosch oil boiler off when my oil tank is being filled?

Yes, Worcester Bosch recommend turning your oil boiler off when your oil tank is being filled and keeping it off for approximately 30 minutes afterwards. This prevents sediment that has accumulated at the bottom of the tank from being disturbed and drawn into the fuel line, which could cause damage to the system.

What should I do if my Worcester Bosch boiler shows an EA error code?

The EA error code on Worcester Bosch boilers typically indicates a flame failure or ignition problem. First, check if you can smell gas. If you smell gas, do not operate any switches, ventilate if safe, leave the property immediately and call the gas emergency line from outside. If there is no gas smell, common causes include a frozen condensate pipe or ignition component faults. During cold weather, check if the condensate pipe is frozen and thaw it with warm (not boiling) water. If the fault persists after thawing, contact a Gas Safe registered engineer.
