If the unit now operates with water flowing, call Technical Service at
1-800-334-3393. Describe what actions were taken and a selection of “flow
restrictors” will be sent to you to replace the one that was removed. This will allow
the unit to operate, but will also control the flow rate to provide the correct rise in
temperature.
If the unit still does not work proceed to step 4.
