The code in one glance
Names: EH1, H1, B1
Message: frequency of power out of limits
Washers: newer-line Electrolux front-loaders, select models only in some entries
The complaint is about electricity coming into the machine, not about a cycle or a hose.
Who does the measuring
The sheet passes the job of measuring frequency and voltage under load to the power company or a professional, so owners stay out of it. If the cord or outlet looks wrong, unplug the washer, and never open the control.
EH1 and other power codes: service in San Francisco
Power codes such as EH1 are handled through our Bay Area line, which serves San Francisco; ring (415) 449-0036 or read Electrolux washer repair. Mention the code and model number, and whether it shows up at start-up.
Model compatibility: Electrolux reuses codes across series and model years, so EH1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
EH1 (H1 or B1) means the frequency of power is out of limits.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
Seeing this code on your Electrolux appliance?
Book a specialist visit for a clear estimate and approval before any repair.
A front-load Electrolux washer showing HO SE has found its supply hoses swapped. Turn the water off, cancel, and put each hose on the inlet it belongs to.
SU dS appears when the washer senses too much foam, so it keeps rinsing until the suds are gone. Confirm the detergent is high efficiency and the dose is small.
You submit a request with your appliance model and symptom, we confirm an appointment window, and a technician performs an on-site diagnosis. You then receive a clear estimate and decide whether to proceed before any repair begins.
Yes. We provide an upfront estimate after diagnosis. No parts are ordered or installed until you approve the work, so there are no surprise charges.
