This is my first post, so I am hoping that someone can help us.
We have a 7-yr old boiler that provides the heating & hot water and a Grohe 1000 thermostatic shower unit.
Over the last year, we have a periodic problem with the shower running cold for a couple of minutes before returning to the set temperature and then worsens over a couple of months to where the ignition system switches off during use and has to be manually reset.
We have had 3 separate engineers attempt to fix the problem. They each replaced different parts (1 replaced the thermistor, 1 changed the main circuit board and the other the water quantity control valve). Each of these interventions has totally resolved the problem for 2/3 months before it gradually deteriorates again to where the ignition system switches off again.
The shower unit has been checked as fully functioning.
We are planning to replace the boiler with a Vaillaint ecotec pro 28 but are unsure if this would solve the problem.
Please can you advise what may be cause of this problem and how it may be resolved.
Thank you so much.
Best regards
