What HO SE
actually means.

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 codeWater 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 toWater supply and shutoff connection

New supply lines from a working quarter-turn stop to each water appliance, tested under pressure.

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.

MakeElectrolux

Electrolux installs take in front-load laundry pairs, freestanding and slide-in cooking, dishwashers and refrigerators, most of them on hookups already in place.

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. 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.

Questions
about HO SE.

Can I clear HO SE myself?
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.

Still showing HO SE?

A booking moves faster with three things: the message exactly as the display shows it, the model number from the carton or the rating plate, and the moment it first appeared. With those, the office can tell whether it is a setup step or a connection to put right, and send the part that fixes it.
