What Does Error Code E30 Mean on an Electrolux Washing Machine?
Check the pressure sensor hose for kinks, blockages, or disconnection — straighten or reattach it and restart the machine to clear the error (takes about 10 minutes).
Fault description
Error code E30 points to a problem with the pressure sensor, also called the water level sensor or pressure switch. This component monitors how much water is inside the drum and signals the control board when the correct level has been reached. When it stops reading accurately, the machine cannot safely continue a wash cycle.
When E30 appears, your Electrolux washing machine will typically pause mid-cycle or refuse to start filling with water at all. In some cases the machine may overfill slightly before stopping, or it may drain and halt without completing the programme. The display will show E30 and the cycle will not progress until the fault is resolved.
The good news is that this fault is often caused by something straightforward — a blocked or kinked hose connected to the sensor rather than a failed component — so it is worth working through the checks below before calling anyone out.
Causes
- Kinked or blocked pressure sensor hose — A small rubber or plastic hose connects the pressure sensor to the drum. If this hose becomes kinked, pinched, or partially blocked with detergent residue or debris, the sensor cannot read air pressure accurately and triggers E30.
- Disconnected pressure sensor hose — Vibration from normal use can cause the hose to work loose from either the sensor or the drum connection point. Even a partial disconnection is enough to cause a false or absent reading.
- Faulty or worn pressure sensor — Over time the pressure sensor itself can fail — the internal diaphragm may crack or the electrical contacts may corrode. When the sensor is no longer able to generate or transmit a signal, the control board logs E30.
- Wiring fault between sensor and control board — The wiring harness connecting the pressure sensor to the main control board can suffer from loose connectors, corrosion, or damaged insulation. A break or poor connection in this circuit produces the same error as a failed sensor.
- Main control board fault — If the control board cannot correctly interpret the signal from the pressure sensor — due to a component failure on the board itself — it will log E30 even when the sensor and hose are in good condition. This is the least common cause.
Step-by-Step Fix
- 1
Power cycle the machine
Switch the machine off at the mains and leave it unplugged for two minutes, then plug it back in and start a new cycle. Occasionally a temporary signal glitch causes E30 and a full power reset clears it without any further action needed.
- 2
Locate and inspect the pressure sensor hose
Pull the machine away from the wall and remove the top panel (usually held by two or three screws at the rear). The pressure sensor is a small round component, typically mounted near the top of the machine, with a thin rubber or plastic hose running down to the drum. Trace the full length of the hose and look for kinks, cracks, or areas where it has been pinched against another component.
- 3
Clear any blockage in the hose
Detach the hose from both ends by gently pulling or releasing any clips. Blow through it to check airflow is clear — if it feels restricted, flush it through with warm water. Detergent residue can build up inside the hose over time and restrict the air pressure signal the sensor relies on.
- 4
Reattach the hose securely
Push the hose firmly back onto both connection points — the sensor and the drum stub — and check that any retaining clips are seated properly. A loose connection at either end is enough to cause a persistent E30 fault. Reassemble the panel and run a short cycle to see if the error clears.
- 5
Check the wiring connections at the pressure sensor
With the machine unplugged, locate the electrical connector on the pressure sensor and unplug it. Check the terminals for corrosion, bent pins, or signs of heat damage. Plug it back in firmly and ensure it clicks into place. Repeat this check at the control board end of the same wiring harness if accessible.
- 6
Test or replace the pressure sensor
If the hose and wiring are both in good condition, the sensor itself is likely faulty. You can test it with a multimeter by checking resistance across the terminals while gently blowing into the hose port — resistance should change as pressure is applied. If there is no change, the sensor needs replacing. Note the part number printed on the sensor body before ordering a replacement.
- 7
Reassemble and run a full test cycle
Once any replacement part is fitted, reattach the top panel, push the machine back into position, and run a full cotton cycle at 40°C to confirm the error does not return. Monitor the machine during the fill phase to check that water stops at the correct level.

When to call a service technician
If you have worked through all the steps above — confirmed the hose is clear and connected, the wiring is intact, and you have fitted a new pressure sensor — but E30 continues to appear, the fault is most likely with the main control board. Diagnosing and replacing a control board requires specialist equipment and carries a risk of further damage if done incorrectly.
You should also contact a service technician if you notice any signs of water leaking from around the drum connection point where the pressure hose attaches, or if you see burn marks or smell burning near the control board area. These situations go beyond straightforward DIY repair.

Frequently Asked Questions
Can I still use my Electrolux washing machine while it shows E30?
It is not advisable. When E30 is active the machine cannot accurately monitor the water level, which means it may overfill or fail to fill correctly. Running a cycle in this state risks water spillage or damage to other components. Resolve the fault first before using the machine again.
How do I access the pressure sensor on my Electrolux washing machine?
On most Electrolux models the pressure sensor is reached by removing the top panel. Unscrew the two or three screws along the rear edge of the top panel, then slide it backwards and lift it off. The sensor is usually a small disc-shaped component mounted on the left or right side near the top, with a thin hose and an electrical connector attached.
Will E30 clear itself after I fix the hose?
In most cases, once the underlying fault is corrected, the error will clear when you power cycle the machine and start a new programme. If the code persists after a confirmed repair, try switching the machine off at the mains for five minutes before restarting. Persistent codes after a repair may indicate a secondary fault.
How much does a replacement pressure sensor cost?
Pressure sensors for Electrolux washing machines are generally an affordable part, though the exact price depends on your specific model. It is worth checking the part number on your existing sensor before ordering to make sure you get a compatible replacement. A service technician call-out to fit the part will add to the overall cost.
Could a blocked filter cause the E30 error code?
A blocked pump filter is more commonly linked to drain-related error codes rather than E30. However, if the machine has been struggling to drain properly over time, excess water or debris could indirectly affect sensor readings. It is still good practice to clean the pump filter as part of your general checks, as it takes only a few minutes and rules out a contributing factor.
