I have a 89 dt55 that sets off the waterflow alarm but the telltale is strong. I replaced the impeller and plate and same thing. The top cylinder seemed very warm, I couldn't hold my hand on it but the bottom 2 seemed cooler. The telltale temp seemed warm enough to wash your hands with.Is this normal?
I gutted the tstat and the alarm went away but of course now i am afraid that it will be to cold. I did test the tstat and it did open at 140 deg. it just seems like the water will not flow until the tstat is open. The other reason I think this is I removed the waterflow sensor when it was running and then replaced it and the alarm went away. Almost like it has an airlock. where should I look or am I just thinking I have a problem?
