HPR prep tables carry a condenser thermistor to catch a dirty condenser or filter. When it reads above its limit for more than two minutes, the display shows E7. Hoshizaki warns that ignoring it can damage the compressor, and the alarm resets once the condenser cools after cleaning. Hoshizaki commercial appliance display What to do when E7 shows on the commercial appliance ### Kind of code Compressor and cooling The unit is running but not moving heat out of the box the way it should. On a walk-in that is often a condensing unit on the roof choking on cottonwood or grease, a condenser fan that stopped, an evaporator fan or defrost heater that failed so the coil iced solid, or a slow refrigerant leak; a reach-in adds a door gasket or heater that lets warm air in. Cleaning the condenser face with the power off and checking that the doors close are fair first steps; the refrigerant circuit, the compressor and every line stay with a technician. ### Usually leads to Walk-in cooler repair Walk-in coolers and freezers back to temperature: evaporators, fans, defrost, drain heaters, condensing units and doors. ### 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 Hoshizaki On a Hoshizaki cold cabinet in a restaurant, the tech first finds out when the last good temperature was written on the log. ### Source Hoshizaki HPR46A, HPR72A and HPR100A prep table service manual (archived copy of the Hoshizaki America PDF) Older Hoshizaki HPR46A, HPR72A and HPR100A prep tables with raised rails, which use a two-character control different from the Steelheart display. ## Before you book, in this order. Each step comes from Hoshizaki's own guidance for E7 on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Wash the condenser air filter and clear anything blocking the grille or the space around it. 02 Make sure the table is not drawing hot air from a fryer, oven or charbroiler beside it. 03 Restart the table and watch whether E7 returns once the compressor runs. 04 Book a visit if E7 comes back after cleaning, since the condenser fan motor may not be turning. ### Still there? It usually turns into [walk-in cooler repair](https://commercialappliancerepair.center/services/walk-in-cooler-repair/). Book with the code and the model number. ### What not to do E7 is not a cabinet temperature alarm, although a hot condenser soon leads to a warm cabinet. It is also different from E9, which reports a failed condenser sensor rather than a hot condenser. ## What you may notice with it. The commercial appliance problems E7 tends to arrive with.

Wash the condenser air filter and clear anything blocking the grille or the space around it. If it comes back, it needs a visit. ### How often should the HPR condenser filter be cleaned? Hoshizaki asks for a check twice a month and a cleaning whenever it is dirty. Kitchens with fryers nearby usually need it more often. ### Will restarting the HPR clear E7? It can clear the display without fixing anything. Hoshizaki notes the alarm repeats once the condenser heats up again, so clean the filter before restarting. ### Can I keep using the HPR while E7 is showing? Hoshizaki warns that ignoring E7 can damage the compressor. Clean the filter, and if E7 returns, move food elsewhere and book a visit. --- **[Read on the site: Hoshizaki E7: the HPR condenser is running too hot](https://commercialappliancerepair.center/error-codes/hoshizaki-e7/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
