Galaxy 600 tumblers use an airflow switch to prove air is moving through the heat path. EAF1 means the switch did not open at the end of the cycle. Huebsch asks for the lint screen and ductwork to be inspected; once the error clears, the control goes back to what it was doing. Huebsch commercial appliance display · also shown as E AF1 What to do when EAF1 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 Huebsch Huebsch machines in an on-premise laundry are often visited when the housekeeping or linen team has finished its heaviest loads. ### Source Huebsch Galaxy 600 tumbler control manual 70474201ENR6 (Alliance Laundry Systems, 2023) Huebsch vended tumblers with the Galaxy 600 control covered by manual 70474201ENR6: single 25 and 30 lb and stacked 30 lb pockets in gas, steam and electric versions. ## Before you book, in this order. Each step comes from Huebsch's own guidance for EAF1 on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Clean the lint screen fully. 02 Check the outside exhaust hood for lint or a stuck damper. 03 Book a visit if EAF1 repeats, since the switch itself may be sticking. ### 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 EAF1 is not EAF2, where the switch never closed after the start. It also does not by itself mean there is a fire risk, although lint-choked ducts should never be ignored. ## What you may notice with it. The commercial appliance problem EAF1 tends to arrive with.

Clean the lint screen fully. If it comes back, it needs a visit. ### Why does a Huebsch show EAF1 only at the end of the cycle? That is when the control checks that the switch opens after the air stops. A sticky switch or trapped lint can hold it closed. ### Do I need to reset a Huebsch after EAF1? Huebsch says the control returns to its previous mode once the error clears. ### Can a blocked exhaust hood cause EAF1 on a Huebsch? Lint in the duct affects how the switch behaves, which is why the manual points to ductwork first. --- **[Read on the site: Huebsch EAF1: the airflow switch stayed closed at cycle end](https://commercialappliancerepair.center/error-codes/huebsch-eaf1/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
