Direct answer
On the covered Whirlpool undercounter refrigerator, E1, E2 and HI or LO mean Whirlpool documents this display on the undercounter refrigerator without stating a cause for it. Treat any cause you find elsewhere as unverified. First, record the exact display and the current temperature setting before resetting.
Definition versus diagnosis
The display names a detected condition—not an automatically failed part.
What this covers
- Whirlpool undercounter refrigerator covered by the cited source
- Displayed code or documented alias: E1, E2 and HI or LO
- The exact operating state described by the manufacturer
What it does not cover
- ×Another product type or original-manufacturer platform
- ×A visually similar but different code
- ×Internal live electrical, sealed-system, gas, battery-cell or control-board repair
Match every character and the exact product
ReversiblePhotograph the complete display and product label. This record covers E1, E2 and HI or LO on Whirlpool undercounter refrigerators. Full-size Whirlpool refrigerators do not display these codes — Whirlpool publishes no consumer error-code list for them.
Preserve the failure state
ReversibleRecord the exact display and the current temperature setting before resetting. Record the operating stage, recent change and what still works before clearing the message.
Correct only the documented fault domain
ReversibleWhirlpool's documented step: power the unit down at the circuit breaker or unplug it, then restore power; arrange service if the code returns. A power reset is the whole of what Whirlpool publishes for this code: remove power for 1 minute, restore it, and watch whether the code returns. If it does, the reset is not the answer and repeating it will not make it one.
Verify once, then respect the service boundary
ReversibleRepeat only the shortest safe action that reaches the original stage. Whirlpool specifies a 1 minute power interruption for this code, not an arbitrary one. If E1, E2 and HI or LO returns, stop repeated resets and use model-specific manufacturer support.
