Hi,My name is ***** ***** I will help with your question. Does the fire cutout and lose all power for a period of time?
Do they come back on after a few minutes?
I think the problem could be down to faulty transducers or the electronic board controlling the mist. The sensors are available as a replacement part here.You will need to check the model number to make sure this is the right part.https://www.uk-spares.com/products/heating/domestic/electric-fires/fire/opti-myst/burbank/bbk20-series-a/dimplex-7511063.html
