Ian - Is it normal for both the water and central heating not to work whilst getting the E20 error?

Help
January 2011
I have got the same problem with my boiler, the E20 pops up. I don't know if this is of much help to you:

http://www.potterton.co.uk/docs/Pot_gold_combi18HEA_Users_sept_10p.pdf

On Pg.8 it basically says, 'E20 Central Heating NTC Fault'.

Awaiting input ...

Thanks.
