Mend Sime Button Boot Unit

Sime Super Four locks out. takes 3-4 times with reset button to boot up?

Unit is 9 years old and locks out most days. Plumber did replace the alternator and checked all. Solved it but the next day it was back to same lock out. Now that CH is on , it is doing it less but still occurring often.

I had the same problem, a sime engineer advised to replace the black ignition box - a FM31 Brahma Box - he actually gave my symtons before i told him about them ie a v common problem. solved it completely.

these people sell them

http://www.theboilershop.co.uk/Boiler_Spares/Sime_Top_10/sime_top_10.html

but can be ordered from local merchants.

If you're getting someone in it may be worth getting them to change the sacrificial anode, only £20 but will make your £400 cylinder (yes, thats just for the cylinder..) last a whole lot longer - ive just changed mine and the old one had completely disintegrated.

hope this helps
