What EP means

EP on GE GeoSpring hybrid water heaters with the text-message display, such as the GEH50DNSRSA and GEH50DXSRGA built about 2012 to 2013, is a status indicator, not a failure. It means the water heater is responding to a utility demand-response energy price signal, with levels such as Low, Medium, High or Critical, received through the communication module. While the signal is active, the unit adjusts how it heats, so you may see EP on the display with no sign of trouble.

Common causes of EP

  • Whether your utility runs a demand-response program
  • Communication module connection
  • The signal level shown
  • Normal heating continuing in the background
✓ One safe check you can try

1. Nothing needs repair; EP is information. 2. Check whether your utility program sends price signals. 3. Expect heating to follow the signal level while it is active. 4. Call us only if hot water stops or the display looks stuck.

! Why to stop there
  • EP should disappear when the signal ends.
  • If it never clears, we look at the communication module.
  • If a normal-looking EP never clears, we check the communication module and its settings.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

EPEP questions
Does EP mean something is broken?

No. It means the unit is following an energy price signal from your utility, so it is a normal operating state rather than a problem that needs repair.

Will I have less hot water?

At higher signal levels the unit may heat differently, so water can recover more slowly. Normal behavior returns when the signal ends, and no action is needed from you.

What if EP never goes away?

Tell us. If the display stays on EP for days with no utility program in place, the communication module or its settings may need a check, and we would test that.
