Coding showing trouble

by Bernard Miller

Spoke with a tech yesterday about the Rheem 6.6 tankless water heater has for the last month been giving trouble codes and stop heating the waater; the codes are 11 and P1.

I checked the screen filter and found nothing blocking flow. Gas is right pressure.

Problem started some time ago and would if allowing water to start slowly I could bring on other appliances without it stopping heating.

Why is it necessary to run the water for some time before seeing the water warming and building in temp; wasting water is an energy loss to someone living with a well; does the heating cooefficient include that?

Possible solution for your Rheem 6.6 water heater
by: Zee from water heaters reviews

Regarding your Rheem 6.6 and coding problem... the best is to have a professional plumber/technician investigate a problem.

I came across this useful website where you can simply fill out a request form and your information will be sent to as many as five plumbers that are serving your area. You can select one you want to deal with. Try.
