Derek Porteous Posted June 3, 2019 Report Share Posted June 3, 2019 I have an Eberspacher central heating system. It’s start up OK but recently has been cutting out completely randomly before its timed sequence of an hour’s running is complete. Sometimes it goes the whole hour and sometimes anywhere within the hour (10 minutes, 30 minutes, 45 minutes, etc.,). It seems to be completely random when it turns itself off. Anyone any ideas what the issue is? Thanks. Link to comment Share on other sites More sharing options...
Grifter Posted June 5, 2019 Report Share Posted June 5, 2019 Do you have a controller with the facility to read fault codes? If you have the 701 controller, see Operating Instructions for how to read them. I found a service cured my similar symptoms after various issues.

(We have been having temperatures in the 20's recently) Link to comment Share on other sites More sharing options...
Derek Porteous Posted June 5, 2019 Author Report Share Posted June 5, 2019 Thanks for replies. I suspect the issue is thermostat related, although we do not have a maximum room thermostat, only a frost control. Guess we need to bite the bullet and get it serviced. We have been advised in the past to make sure we run it at least once a month and then leave it along until it breaks down! Link to comment Share on other sites More sharing options...
Bobbybass Posted June 6, 2019 Report Share Posted June 6, 2019 (edited) You could try the fuel filter. It's so tiny you can hardly see it...about 4mm wide and 6mm long. It's in the clicking metering pump...where the fuel pipe attaches. You have to remove the inlet pipe and poke about with your nail to get it out. it's like a tiny thimble. Worth a check before you commit to expense. Edited June 6, 2019 by Bobbybass Link to comment Share on other sites More sharing options...
