Electrolux states that HO SE means a condition is detected where the inlet hoses have been installed incorrectly — hot supply to the cold inlet and cold supply to the hot inlet. Electrolux appliance display What to do when HO SE shows on the appliance ### Kind of code Water supply and drain The new appliance is reporting what it gets from the water connections behind it. A no-water or slow-fill message on the first fill usually means the supply valve is still closed or only half open, or the new line kinked when the unit slid back; a drain message means the drain hose is pinched, pushed too deep into the standpipe, or looped higher or lower than the installation instructions allow. Open the valve fully, straighten the hose, set it to the height the manual gives, and run the cycle again. ### Usually leads to Water supply and shutoff connection New supply lines from a working quarter-turn stop to each water appliance, tested under pressure. ### Shows up as Appliance Installation Code on a New Unit: Setup Modes and Hookup Messages An appliance installation code is a message a new unit shows because of how it was set up: a demo mode, a water or drain alert, a vent warning or a power check. ### Make Electrolux Electrolux installs take in front-load laundry pairs, freestanding and slide-in cooking, dishwashers and refrigerators, most of them on hookups already in place. ### Source Electrolux owner support: HO SE error code, front-loading washer Confirmed on Electrolux’s front-loading washer support article, which names this code specifically as reversed-hose detection. ## Before you book, in this order. Each step comes from Electrolux's own guidance for HO SE on its appliances. Follow it to the end: the last card says whether this is a visit. 01 Shut off each water supply valve before touching either hose. 02 Attach each supply hose to the correct inlet connection on the washer — hot to hot, cold to cold. 03 Turn the supply valves back on and confirm neither hose is kinked. 04 Run a short cycle to confirm the code clears; if HO SE returns with the hoses confirmed correct, book a visit. ### Still there? It usually turns into [water supply and shutoff connection](https://applianceinstallation.center/services/water-supply-and-shutoff-connection/). Book with the code and the model number. ### What not to do HO SE is specifically about hose placement, not a failed inlet valve or a heating problem. If the hoses are already correctly connected and the code repeats, that points to a different issue. ## What you may notice with it. The appliance problems HO SE tends to arrive with.

Shut off each water supply valve before touching either hose. If it comes back, it needs a visit. ### My newly connected Electrolux laundry machine shows HO SE — what does that mean? Electrolux’s control detected the hot and cold supply hoses connected to the wrong inlets. Shutting off both valves and reattaching the hoses to the correct sides clears it. ### Is HO SE a sign my Electrolux laundry machine’s water valve is broken? Not based on Electrolux’s own description — the code is specifically a reversed-hose detection, so checking the hose connections comes before suspecting the valve itself. ### Will HO SE clear on its own if I run another cycle on my Electrolux machine? No — Electrolux’s fix is to physically correct the hose connections; the code will keep returning on a hose mix-up until the hoses are swapped back. --- **[Read on the site: Electrolux HO SE: the hot and cold hoses were connected backward](https://applianceinstallation.center/error-codes/electrolux-ho-se-reversed-hoses/)** **[Book a visit with ApplianceInstallation.center](https://applianceinstallation.center/schedule/)**
