UniMac's auto leak detection watches the level while valves are closed. A falling level means water is escaping, usually through the drain valve. When it happens in a cycle, E Ld is shown for one minute after the door is opened at the end. UniMac commercial appliance display · also shown as ELd What to do when E Ld shows on the commercial appliance ### Kind of code Water, fill and drain Water is not arriving, not reaching its level, not heating or not leaving on time. A dish machine may be short of fill because a supply valve is half closed or its line strainer is clogged, it may drain slowly through a scrap basket full of debris, or its booster may be too scaled to heat the rinse; a combi's steam generator may be scaled or its water treatment exhausted; a washer-extractor may time out on a slow drain. Opening the supply valve, cleaning strainers with the unit off and checking the drain line are fair; a pump, a fill valve, a heater or a leak near wiring is a visit. ### Usually leads to Dish machine repair Undercounter, door-type and conveyor dish machines: tank heaters, boosters, wash pumps, fill and drain valves. ### 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.

Note the code and let the cycle finish; the laundry is still washed. If it comes back, it needs a visit. ### Does E Ld mean my UniMac is leaking on the floor? No. It means water is escaping through the drain valve during the test. Check the floor anyway if you see puddles. ### Why does a leaking drain valve matter on a UniMac? Wash water and chemistry drain away mid-step, so the machine refills more often and wash quality drops. ### How do I clear E Ld on a UniMac? It clears after a minute or when the machine is powered down, but the valve still needs attention. --- **[Read on the site: UniMac E Ld: the leak check found a leaking drain valve](https://commercialappliancerepair.center/error-codes/unimac-e-ld/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
