Tigger Posted January 15, 2019 Report Share Posted January 15, 2019 Hi, We have a webasto heater which was working fine until recently. We then had some new radiators fitted. Unfortunately they leaked, which drained the system. Unsurprisingly the heating stopped working. We called in a webasto engineer who replaced the water pump and another part. The diagnostic report doesn't mention the water pump but does mention the heater over-heating at some point. The engineers opinion is that it was the water pump running dry that burnt out and in doing so triggered another system to fail. The people that fitted the radiator are denying it has anything to do with them, and even had the cheek to criticise the webasto engineer and his opinion. The've also been to fix the radiator twice and failed. What happens if one runs the system with no water? I'm assuming this is not a good thing - but how do I go about proving that a drained system caused the webasto to fail? Link to comment Share on other sites More sharing options...
Boater Sam Posted January 15, 2019 Report Share Posted January 15, 2019 Webasto engineers written report and invoice? County Court action. Can't sue on an estimate. Concentrates the minds wonderfully. But did you not notice the leak and that there was no water? There is a duty for you to ameliorate any damage/loss.

ditchcrawler Posted January 15, 2019 Report Share Posted January 15, 2019 You will kill it if you run it with no water,would you try and boil an electric kettle with no water in it. Link to comment Share on other sites More sharing options...
Tonka Posted January 15, 2019 Report Share Posted January 15, 2019 I would have thought that the Webasto ECU would have shut the Webasto down because of an overtemp Link to comment Share on other sites More sharing options...
