Dexter T-Series machines continue the cycle after F8 but will not spin until the tub is empty; if it never empties, the machine tumbles through the spin time instead. The drain valve, pressure switch tube and switch are Dexter's list of causes. Dexter commercial appliance display · also shown as SLOW DRAIN ERROR What to do when F8 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 Dexter A Dexter call in a laundromat is often set for opening time, before customers load the row and every pocket of the room is in use. ### Source Dexter common troubleshooting and error code reference for T-Series vended front-loads (Part 8533, 9/19) Dexter T-Series vended front-load machines (T-300 through T-1450) covered by Dexter's 2019 troubleshooting reference; the drive codes come from the variable frequency drive these models use. ## Before you book, in this order.

Check the floor drain or trough for backup. If it comes back, it needs a visit. ### Why did my Dexter tumble instead of spinning after F8? Dexter will not spin with water in the tub, so it agitates through the spin time when the tub never empties. ### Can lint cause F8 on a Dexter? Lint and small items at the drain valve are common reasons for a slow drain. ### Is F8 on a Dexter the pressure switch? It can be, if its tube is blocked or the switch misreads. That is checked inside the machine. --- **[Read on the site: Dexter F8: slow drain, the tub took over 7 minutes to empty](https://commercialappliancerepair.center/error-codes/dexter-f8/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
