FAQ
TL;DR: Error 02 on Electrolux ESL65070R often traces to a clogged hydrostat hose/chamber; one user verified “heater works – 28 Ω.” “Heater works – 28 Ω.” [Elektroda, foxlis, post #21691385]
Why it matters: This FAQ helps DIYers restore fill/heating by cleaning the hydrostat path or replacing the set if needed.
Quick Facts
- Typical symptom: machine keeps draining, won’t refill, then shows Error 02. [Elektroda, bowler, post #17357398]
- The small hose between the bowl and right‑side hydrostat is the key clog point; unplug it to clean. [Elektroda, peter falk, post #16707244]
- Effective field fix: “Hot water and a syringe” to flush the hydrostat path. [Elektroda, peter falk, post #17360521]
- Boiling‑water flush restored full flow and the unit ran 5–6 cycles OK. [Elektroda, bowler, post #16734864]
- Hydrostat unit is not serviceable; replace the set if cleaning fails. [Elektroda, mrice, post #17357679]
What does Error 02 mean on the ESL65070R?
It indicates the control thinks the tub hasn’t filled, so it keeps draining and aborts. Users report constant pump‑out with no water intake before Error 2. This points to a pressure/level sensing issue, usually the hydrostat path clogging, not the inlet valve. [Elektroda, bowler, post #17357398]
Where is the hydrostat chamber and hose?
The hydrostat assembly sits on the right side. A small hose links it to the bottom bowl (sump). Cleaning involves unplugging that hose, as confirmed by service replies in the thread. [Elektroda, peter falk, post #16707244]
How do I clean the hydrostat hose and chamber?
Three steps: 1. Unplug the bowl‑to‑hydrostat hose. 2. Flush the path using hot water with a syringe until flow is clear. 3. Refit and test a short cycle. Experts summarize it as: “Hot water and a syringe.” [Elektroda, peter falk, post #17360521]
What if the hose looks clean but Error 02 persists?
Debris can sit in the bowl port or chamber. Pour boiling water into the bowl and let it drain through the hose into a container, repeating until a full stream appears. One user saw muddy water, then normal flow, and five to six good washes. [Elektroda, bowler, post #16734864]
Do I need to calibrate sensors after cleaning?
In this thread, the practical fix was only mechanical cleaning. No calibration steps were required or reported to solve Error 02 for these cases. [Elektroda, bowler, post #16734864]
What is the hydrostat on this dishwasher?
It’s the pressure‑sensing unit that reads water level via the small hose from the bowl. In the ESL65070R, helpers identify it on the right side, connected by that single hose. [Elektroda, peter falk, post #16707244]
Can the hydrostat be disassembled and cleaned internally?
No. A pro in the thread states the hydrostat is not meant to be opened. If the path is clear and errors persist, replace the hydrostat set. [Elektroda, mrice, post #17357679]
My dishwasher sometimes recovered after sitting for days—why?
Moisture and debris can shift as the machine dries. One user noted errors stopped after the dishwasher sat 5–7 days, then returned. That pattern fits a partial clog in the sensing path. [Elektroda, bowler, post #16699951]
How can I quickly confirm the hose is the issue?
Disconnect the bowl‑to‑hydrostat hose and push hot water through with a syringe. If resistance drops and flow becomes steady, you’ve cleared the blockage, a known successful field check. [Elektroda, peter falk, post #17360521]
When should I replace parts instead of cleaning?
If repeated flushes don’t restore normal filling or Error 02 returns quickly, replace the hydrostat set. The thread’s expert explicitly recommends replacement when cleaning won’t hold. [Elektroda, peter falk, post #17360521]
What is the turbidity (water purity) sensor and should I clean it?
It’s the “red” sensor in the sump that reads water clarity. A user cleaned it by hand, but Error 02 still required hydrostat‑path cleaning. It’s secondary to the level issue here. [Elektroda, bowler, post #16700049]
My heater tests 28 Ω—does that rule out heating faults?
A participant measured “heater works – 28 Ω.” That confirmed heating hardware on fast cycles, while fill/level issues blocked heating on others. Use 28 Ω as a sanity check, not the sole diagnostic. [Elektroda, foxlis, post #21691385]
What’s a tacho coil in this context?
It’s the motor speed feedback coil. One user planned to check it only after verifying sensors, relays, and the hydrostat path. Prioritize clearing Error 02 first. [Elektroda, foxlis, post #21691385]
Why does fast program heat but others don’t?
A user observed fast mode heating while others didn’t, suggesting program logic depends on sensor confirmations. If level sensing fails, the controller may inhibit heating. Fix the hydrostat path first. [Elektroda, foxlis, post #21691385]
Edge case: the hose is clear but it still drains—what next?
The chamber port can clog while the hose stays clear. Boiling‑water pours from the bowl side freed a hidden blockage and restored full stream in the reported case. [Elektroda, bowler, post #16734864]
Can I mute or restore the dishwasher’s beeps?
Yes. The thread shows a control screen indicating audio settings; the original poster adjusted them using the pictorial cues despite language differences. [Elektroda, bowler, post #17327962]
