No Error Code & No Hot Water
(Remote Control Displays Hot Water Temperature Setting)
Explanation: No hot water is delivered when water is flowing through unit and Remote Control displays the hot water
temperature setting.
Possible Causes:
•
Water Flow
•
DIP 1 Setting On Main Control Board (PCB)
• Water flow sensor
Water Flow:
1. Turn OFF water supply to unit. Turn Remote Control OFF; unplug power cord at wall outlet. Wait 10 seconds; plug
power cord back into outlet; wait 20 seconds; turn the Remote Control ON. Turn water supply ON; check the nearest
hot water fixture for hot water. If you have hot water, then the unit needed to be reset.
2. Water flow might be too low. Open multiple hot water fixtures. If unit fires then there is not enough water flow to
engage the unit at a particular fixture. Check your fixture aerator screen(s) for debris. Clean if necessary.
3. Your water lines might be crossed. Make sure your hot and cold water supply lines are connected to the appropriate
hot and cold water assembly connections on the unit.
4. Your water flow may be restricted by a debris in Water Filter. Remove the water filter and inspect. Clean if
necessary.
Dip 1 Setting:
All Dip 1 switches must be in the ‘OFF’ position.
Manifold Units ONLY: Go to Error Code 03 to verify proper DIP 1 setting
