On UniMac extractors with a temperature sensor, E SH turns off heating and all sensor-based steps for the rest of the cycle. The sensor, its wiring or water in a connector can cause a shorted reading. UniMac commercial appliance display · also shown as ESH What to do when E SH shows on the commercial appliance ### Kind of code Sensors and probes A probe is handing the controller a reading it cannot trust, or none at all: a box or coil sensor torn loose from its clip, a fryer probe coated in carbon from oil left too long between filterings, a combi core probe with a kinked cable, or a connector gone green from steam and cleaning chemicals. The unit then runs on, stops, or shuts the heat or the cooling off to protect itself. Letting it cool and restarting it as the manual describes is fair; a probe that still reads wrong sits behind a panel, and that is a visit. ### Usually leads to Commercial controls and board repair Controllers, touch panels, relays, contactors and interlocks tested, and replaced only when the evidence says so. ### Shows up as Commercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display 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. ### Make UniMac UniMac equipment in a facility laundry room is usually serviced after the heaviest morning loads are out. ### Source UniMac UW-series washer-extractor control manual F8552201R2 (Alliance Laundry Systems, 2017) UniMac UW-series hardmount extractors of 45 to 130 lb (UWH, UWL, UWN and UWU models) with the keypad control in manual F8552201.

Each step comes from UniMac's own guidance for E SH on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Let the machine finish and check whether the load needs rewashing. 02 Power it down and up to see whether the reading returns to normal. 03 Book a visit if E SH comes back, since the sensor is reached from inside the cabinet. ### Still there? It usually turns into [commercial controls and board repair](https://commercialappliancerepair.center/services/commercial-controls-and-board-repair/). Book with the code and the model number. ### What not to do E SH does not mean the machine is dangerously hot; the reading itself is the problem.

Let the machine finish and check whether the load needs rewashing. If it comes back, it needs a visit. ### Is my UniMac actually at 220°F when it shows E SH? No. Water in the cylinder cannot reach that; the control is reading a shorted sensor circuit. ### Will a UniMac keep heating after E SH? No. The heater and temperature steps are disabled until the machine is powered down and the sensor reads correctly. ### Can a leak cause E SH on a UniMac? Water reaching a sensor connector can short it, which is one more reason to check for drips inside the cabinet. --- **[Read on the site: UniMac E SH: the temperature sensor reads shorted](https://commercialappliancerepair.center/error-codes/unimac-e-sh/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
