Noisy heater slash a/c searay 410

[beachnut]

The system is making a noise similar to a dishwasher in it's wash cycle (kind of droaning). Just deweinterized and both forward and aft are doing the same thing independently as well as together. Could it be air in he lines? I opened the sea cock strainer checked if any debris and it is clean. Any one have any ideas?:smt100 Beach nut

I could be totally wrong, but if you are in Missouri like I am, the water temp must be mid-high thirties. My guess is both units are running pretty hard to generate some heat because of the cold water. Heat mode has a different sound to it. Were you able to get some heat out of those?

Actually they started working rather well the next day and I seperated the tubing so it would not touch any other part of the unit compressor,tubing ext. and that helped in getting rid of 90% of the noise from vibration. Every thing was great for about 12 hours and as luck would have it he hot water heater stopped working.:smt089 Beachnut
