I had it in garbage pail up to the top of lower unit. Grommets and tubes look good, replaced impeller with model number from parts catalog. Existing impeller looked good and housing appeared in good shape, don,t think the problem is there.Had this problem when I first got it and before I removed the lower housing. Heads were getting hot , so I shut it down each time, but not too excessive to peel paint.so I believe im not getting circulation, I will check thermostat. Should I temporarily remove it and then try?
