Fault or breakdown

This boiler is supported in mainland UK by Worcester, Bosch 
Group, part of Bosch Thermotechnology Ltd.

Specialist service engineers are available to attend a 
breakdown occurring on this appliance.

No charge will be made for parts and/or labour providing:
An appliance fault is found and the appliance is within the 
guarantee period. Reasonable evidence of this must be 
supplied on request. i.e. the Benchmark Checklist.

A call-out charge will be made where:
– The appliance is outside the guarantee period.
– Evidence cannot be provided that the first year service 

inspection has been carried out (i.e. an entry in the 
Benchmark Checklist).

– Our Field Service Engineer finds no fault with the 

appliance.

– The cause of breakdown is misuse or with other parts of 

your plumbing/heating system, or with equipment not 
supplied by Worcester, Bosch Group.

If the boiler fails to give complete satisfaction, please 
check the following points before calling for a service 
engineer:

1. Oil level in the tank
2. Power to the boiler
3. All control settings
