I have a 2 year old unit that has worked great until recently. I was running it on reverse cycle when I noticed it wasn't heating
the boat very well. It was showing an error code for low charge.
I removed the unit and had a friend who is in the marine
air business install ports
. The Webasto unit came new without ports
. He had trouble getting the ports to seal because there is very little room to work. Anyway, he finally got a seal on the ports. But, the unit is still losing charge at the rate of 1 lb every 10 minutes. I removed all electronics
and put the entire unit in a tub of water
. No bubbles, put it is still losing charge at 1 lb. per 10 minutes.
How can I find a leak that doesn't produce bubbles under water
. I know there is a dye and I would try that if the leak was really slow.
Is there any way the unit can lose charge inside itself?
BTW, I bought this unit new for half price
because it had been in storage
for 4 years so, no warranty
