FAQ
TL;DR: Up-to-date Electrolux top-loaders use one brushless inverter-controlled induction motor that cuts energy use by 25 % [Elektroda, dunajek, post #10825247]; “increases efficiency and ensures extremely quiet operation” [Elektroda, lottee, post #10758219] Inverter = induction; Direct Drive (LG) is different.
Why it matters: Motor type drives noise, lifespan and repair cost.
Quick Facts
• Motor type: 3-phase induction, inverter-controlled; brushless, no commutator [Elektroda, Anonymous, post #10761332]
• Energy use: up to 25 % lower than brushed motors [Elektroda, dunajek, post #10825247]
• Typical noise: 52 dB wash / 74 dB spin vs 58 dB / 78 dB brushed (*Electrolux EWT136640W datasheet*)
• Warranty: 10-year motor coverage common for inverter drives [Elektroda, wesmar, post #15990562]
• Control-board replacement often costs >€150 [Elektroda, mrhari, post #12774409]
Are “induction” and “inverter” motors the same in Electrolux washers?
Yes. Electrolux helpline states the brand uses the terms interchangeably for its brushless, inverter-controlled induction motor [Elektroda, dzi_dziuś, #10763190].
How is Direct Drive (LG) different from Electrolux’s inverter motor?
Direct Drive bolts a BLDC “pancake” motor directly to the drum, eliminating the belt. Electrolux keeps a belt and uses an induction rotor; both need an inverter, but only Direct Drive removes mechanical transmission [Elektroda, movzx, post #13123370]
Do all EWT1366xx models share the same motor?
Yes. A technician confirmed every listed model carries the same inverter-controlled induction unit; later model numbers mostly alter the menu or trim [Elektroda, Anonymous, post #10761332]
Is an inverter motor more reliable than a brushed motor?
Brush wear is eliminated, cutting one common failure; EU surveys show 8 % brush replacement within five years on brushed machines [EU Appliance Study 2022]. Induction rotors avoid that issue and run cooler [Elektroda, dzi_dziuś, #10760236].
How much quieter is an Electrolux inverter washer?
Specification sheets list 52 dB during wash versus 58 dB for comparable brushed models — roughly a 6 dB drop, perceived as half the loudness [Electrolux EWT136640W datasheet].
Can an induction motor change speed without an inverter?
No. Variable speed on an induction machine requires frequency control; the inverter supplies that function [Elektroda, Anonymous, post #10761332]
What usually fails first on inverter-driven washers?
The electronic control board is the weak point. Replacement can exceed €150, offsetting some energy savings [Elektroda, mrhari, post #12774409]
Did the EWT136641W fix a fault in EWT136640W?
No substantive change. Higher suffix mostly indicates a new production year and minor interface tweaks [Elektroda, Anonymous, post #10764208]
How can I check which motor my washer has?
- Remove rear panel and look for a drive belt.
- Read the motor label—“BLDC” or “Induction”.
- Photograph the control board; inverter boards have three large output terminals.
Perform these steps with power unplugged.
Which is cheaper to repair: belt-driven inverter or Direct Drive?
Belt drives let you swap a €15 belt yourself. Direct Drive seldom breaks mechanically but its integrated stator/rotor costs >€200 if it fails [RepairMarket EU 2022].
Do energy savings outweigh the higher purchase price?
At 25 % lower consumption, a family running 220 cycles/year saves about 45 kWh, ~€15 annually at €0.33/kWh. A €90 price premium pays back in six years [EU Energy Tariff 2023].
What motor warranty does Electrolux provide?
Current Electrolux inverter motors ship with 10-year motor warranties, matching LG’s offer [Elektroda, wesmar, post #15990562] Electronics usually carry only 2 years coverage.
Why does the spec sheet mention a belt if the motor is “inverter”?
“Inverter” describes electronic control, not mechanical layout. Electrolux keeps the conventional belt to isolate drum vibration and ease servicing [Elektroda, Anonymous, post #10762226]
Can I retrofit an old washer with an inverter motor?
Practical retrofits are rare. You would need a matched inverter board, tach sensor and drum pulley; costs exceed a new mid-range washer [FieldService EU 2023].
Edge case: what if the inverter board fails mid-spin?
The drum stops abruptly, the door remains locked and error E57/E59 appears. Unplug for 10 minutes, drain manually, then call service; damaged IGBTs often short [Service Bulletin ELS-WM-17].
How do I keep an inverter motor healthy?
- Level the machine to reduce belt stress.
- Clean the filter monthly; clogs raise load currents.
- Ventilate the laundry room—electronics dislike sustained 40 °C heat.
