Worcester Bosch call their Greenstar boiler heat exchangers heat cells.This type is found on the Greenstar i Juniors, Greenstar i, Greenstar Ri and the Greenstar Si boilers.

Worcester Bosch call their Greenstar boiler heat exchangers heat cells.This type is found on the Greenstar i Juniors, Greenstar i, Greenstar Ri and the Greenstar Si boilers. Cleaning the "heat cell" is from the top, the fan, air gas manifold and burner clamp have to be removed to gain access to the burner gasket, electrodes and the baffles housed in the heat exchanger. Not the best of designs for servicing, but still a lot working after 15-20 years. The modern boilers still have these type of heat cells but have more efficient pumps and better software menu system.

As the name suggest these boilers are very compact, designed to fit in to a kitchen cupboard, but not with the service engineer in mind!
These heat cells are found in Greenstar Compact CDi, Si and system i boilers.

Cleaning the inside of the heat cell is done after the removal of the fan and burner housing.
The electrodes are positioned on the left hand side of the heat cell, which has limited space for their removal... These modern boilers have a menu system that allows the engineer to run certain component tests, smart!

The big Daddy of the all Greenstar boilers.
Most engineers love working on these boilers, plenty of room to get your hands in and around all the parts. Typically found in larger properties with well designed boiler compartments. This hea tcell is found in all the older classic CDi boilers and the more modern Greenstar 8000 type boilers

Access to the burner is made after the removal of the fan, air gas manifold and burner plate at the top. The electrode are in the front, nice and easy, the photo shows the old type electrodes with the sight glass, these have to be changed to all metal type for safety reasons.
Access to the heat exchanger is below the electrodes via a plate again easy!

Reliable boiler fault finding and repairs
Your Trusted Worcester Bosch boiler Experts - Plumbright Services Ltd
Worcester Bosch Greenstar boiler have gone from the early models with blue flashing diagnostic lights to the more modern boilers that show a comprehensive digital fault code on display.
Some typical faults on display when repairs servicing include:-
Slow blue flashing neon light, I would check that gas was at the gas valve and it was operating correctly, the spark and ionisation electrodes would need to be inspected in case of damage, getting to the electrodes would involve removing the fan, air-gas manifold, burner clamp plate etc, I would suggest a full heat exchanger service be conducted, taking advantage of the now access to the heat exchanger. New burner gaskets and electrodes usually fix this issue on a worcester boiler
Fast Blue flashing neon light, the fan is usually the suspect here.
Modern boilers with EA on display, flame not detected, could be blocked or frozen condensate drainage, flue blocked or electrodes again.
E5 218 Flow temperature too high, Fan defective or blocked circulation.
E9 224 Flue thermostat or high limit thermostat activated.
Remember not all heating and hot water issues relate to boilers, you may have a problematic time clock or central heating programmer, the room thermostat may have gone high resistance or the 2 port 3 port valve stuck in one position. I have the skill and knowledge to solve your problem quickly.
