What it is

The Worcester Bosch 7733600091 is a cleaning kit intended for the heat exchanger on Worcester Bosch Greenstar appliances. It is supplied as a service item for use during maintenance, when scale, sludge or combustion debris has built up on the heat exchanger surfaces. Keeping the heat exchanger clean restores heat transfer and helps the appliance run at its designed output.

Signs this part needs replacing

  • Kettling, banging or rumbling noises from the heat exchanger during firing
  • Repeated overheat lockouts or high limit trips after the appliance has run for a while
  • Visible scale, sludge or black oxide debris on the heat exchanger surfaces at service
  • Heating circuit warming more slowly than expected with no other obvious cause
