BAXI 105HE - nothing!!! (18 months old)

[jusvm]

HI,

We have a Baxi 105HE which decided to go mad the other day (Easter Sunday)

Have changed pressure valve and fuse, but still refusing to fire up.

Have tried to reset - but it won't

So, fiddle around inside and get it to switch on - but as soon as hot water turns on - it goes on strike and fails to light back up. So, wake up every morning with no hot water, no heating and a very grumpy family.

Pressure is OK (about 1.6), and rads are fine

Please help - I am loosing the will to live
