What uHi
actually means.
The Cross Temp control blinks uHi when the line voltage rises above its set limit. The alarm is always active. High voltage heats motors and can harm the control, so it is worth finding quickly.

What to do when uHi shows on the commercial applianceKind of codeControls and power
The controller itself is reporting trouble, or the supply behind it is: a display with dead segments, a keypad that stopped responding after steam or degreaser got behind it, relays that stick, stored recipes or cycles that vanished overnight, a blown control fuse, or one leg of a three-phase feed missing so half the heat or the pump is gone. A full power cycle at the breaker, done as the manual describes, clears a passing glitch; a code that returns, a scorched smell or any sign of moisture behind the panel means the breaker stays off, and that is a visit.

Controllers, touch panels, relays, contactors and interlocks tested, and replaced only when the evidence says so.

A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone.

It usually turns into commercial controls and board repair. Book with the code and the model number.
What not to do
uHi is not a temperature alarm and not a failed control. Its opposite, the low voltage alarm, is uLi.

A booking with a code goes further when it has the code as shown, the model and serial from the data plate, and a word on whether the unit still holds temperature, heats, rinses or spins. With those three, the office can match the likely part to your unit the same day.
