Potterton Boiler 100e?

The boiler on a daily basis discharges water to the outside. The temp goes above 3bar and then falls when not running to below 1bar. Any ideas what is going on?

A rubber internal gland has ruptured. It will need replacing or an external expansion tank (the size of a small football) will need to be attached.

The same thing happened to mine last year - it's now fine.
