Low pressure LED on Puma 80e

[Oddsocks]

When your request for help goes into forgotten world of past pages without resolution. You know you've got a serious problem.
Having carried out all the recommendations at a cost of;
Modulation board £115.00+ vat = £135.12
Pressure switch £ 14.21+ vat = £ 16.70
Total cost £151.82
And the dreaded RED LED is still lit up. No H/W No C.H.

To those who helped me; a Sincere Thank You

It would be unfair of me to name the person who was doing his best to help me. But he told that if I carried out a test the circuit board is faulty. By circuit board I take it he meant the Modulation board.
Here's part of the massage;

If you still get the low pressure neon on after this then the problem def. lies with the circuit board.
ps make sure the boiler is filled before linking the switch.

N.B. The test he advised was carried by a Time Served Electrician. Not Me

Anyway thanks for responding perhaps you can give me a little help because I need it and quite frankly, I'm totally ****ed off.
