What E Ht
actually means.
UniMac extractors with a heater raise the bath to the temperature the cycle calls for. If that takes longer than the heat alarm time, E Ht shows and the heater output is switched off for the rest of the cycle, so the load finishes cooler than planned.

What to do when E Ht shows on the commercial applianceKind of codeTemperature and alarms
The controller has seen a temperature outside the band it was set for and is saying so: a box above its alarm point, a fryer vat or an oven cavity that tripped its high-limit, or a dish machine rinse that never came up to heat. Often the cause sits outside the unit, such as a door left open during a delivery, a coil packed with grease, a kitchen far hotter than the maker allows or a booster fed cold water. Checking the door, the coil and the air around the unit is fair; move the product if a cold box stays above 41°F, and book the visit.

Before you book,
in this order.
Each step comes from UniMac's own guidance for E Ht on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Let the cycle finish and note whether the load needs rewashing for linen that must be hot-washed.
Check that the hot water supply is actually hot, since cold inlet water makes the heater work far longer.
Book a visit if E Ht repeats; heater elements and their contactors are behind the panels.

What not to do
E Ht does not mean the machine is overheating; it means it could not heat enough. It applies only to UniMac machines with an internal heater.

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.
