H87 D135 Heater lock-out permanent

Permanent heater lock-out has been activated

1) Delete heater lock-out - attempt restart

2) Read out additional fault messages and work through their recommendation for action

thankyou for that, have been on that site etc, the problem I've got is that I have no additional fault messages so d'nt know where to start, it does mention taking the fuse out for 10 seconds but again I cannot seem to find even that.

In a correctly installed system it will be near the batteries.  There is a dedicated fuse holder in the wire that runs from the Webasto to the batteries.

I have the same problem. H87 error. I deleted the error code and removed the fuse. It still comes up every time I try to start my Thermo  Top Evo. Does it mean permanent lock out?

According to 5.1.1-5 in the above manual, yes.
