Apollo 30/50B blowing fuses

[RatMan]

Can anyone help me please.

I have inherited an Apollo 30/50B boiler with the house I bought 2 years ago. Everything was fine until now.

The boiler stopped working had an engineer round to fix it which was apparently just the fuse to the electric switch for the boiler. This was replaced and everything was fine for 2hrs then the boiler stopped working again. I have replaced the fuse 4 times with the same type (3A) that the engineer put in but it just blows them immediately. Can anyone offer a solution.

is the pump wet?

Not that I or the engineer can see.

Are there any drips onto the M/Vs ?

Disconnect components and then reconnect one at a time to save on fuses !!

check the suppressor, behind the hi/lo/off switch.

will get the engineer to try both of those suggestions.

Does this happen when the boiler is on heating, hot water of both?
