Bosch greenstar 30 CDi - no central heating or hot water!

I had a brand new boiler installed by a recommended supplier in September 2008. It failed to heat the hot water . After some time and aggravation we were advised a new pump was required. This was fitted in November. By December it was not working again and we were getting no hot water from the boiler and by January 5th the central heating system was not working either. The lights are on, on the control panel.

It sounds like the system was not cleaned properly when the new boiler was fitted. all new boilers need to have the pipework flushed to remove any debris scale sludge and flux from the system. this is now usually done by a power flush which is basically a big pump mounted on a big bucket and it washes the dirt out of the pipework and collects in the bucket. if this is not done the dirt will block up the small passages in the heat exchanger. i suggest the system is cleaned flush and the heat exchanger changed to help protect the boiler a filter should be fitted (for example a magna clean) if the company who installed the boiler is corgi registered then they are liable for the damages. call corgi for advice.

Boiler bangs when hot water used


You need to install a "water hammer arrestor" they can be found at any local plumbing supply house.

If you can find one with "Shark bite" fittings already installed then there will be no need for soldering or special tools other than a tubing cutter.

having found a circuit diagram, realised that the divertor valve was electrically operated.i unplugged this then unclipped the motor from the valve body,the diverter valve is spring loaded and once i'd removed the motor the spring raised the valve to divert water through the dhw heat exchanger,giving us hot water but no heating, if i refit the motor the problem comes back heating no dhw.ordered new motorised valve assembly £30 next day order .
this was a simple fix without having to drain the system down.

My Worcester Bosch Greenstar Combi boiler digital display has started flashing the temperature then two half-rectangles alternately ... it is not heating the radiators to full capacity - any ideas?


just had same problem.  this apprently happens if the power supply has been interrupted or you switch the power on and off.
• The boiler runs for 15 minutes at minimum heat output to fill the condensate trap, the display (K) alternates between -II-” and the boiler flow temperature. This occurs every time the mains supply has been interrupted.
