E4
Candy E4 on washing machine: excess foam or high water level
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On Candy washing machines, E4 or E04 (and 4 LED flashes with 5-second pauses on models without a display) means there is too much foam and/or water in the drum. Check that you are using the right dose of machine detergent; if E4 returns on an empty rinse, contact a technician.
Safety first
Stop and check this first
- Before unscrewing the lower drain filter counter-clockwise to clean it, always make sure there is no water remaining in the drum, and refit the front filter tightly to prevent water leaking onto the floor.
- If you see the drum continuing to fill with water past its normal level when E4 or E04 is displayed, close the water supply tap and unplug the washing machine from the wall socket before calling service.
Safe checks you can perform
- Verify detergent suitability and dosing for the programme
- Clean the detergent drawer and run an empty rinse cycle
- Clean the lower water filter and unplug for 1 minute to reset
- Authorised inspection of the water fill valve and level control
Leave these tasks to a qualified professional
- Do not attempt this professional task: Replace a defective water fill valve causing drum overfilling
- Do not attempt this professional task: Clear the water level sensing pathway and verify foam drainage
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Replace a defective water fill valve causing drum overfilling
What they doWith the washing machine unplugged and the water tap closed, the authorised technician tests the water inlet fill valve and, if it allows water to exceed the maximum level for normal operation, replaces it with an original Candy spare part.
They must show youthe replaced fill valve and the drum filling to the normal water level without overflowing or showing E4.
In writingthe E4/E04 code, replacement of the fill valve with its original part number, and leak test of the hose seal.
Clear the water level sensing pathway and verify foam drainage
What they doIf the fill valve shuts off properly but E4/E04 persists after cleaning the drawer and filter, the authorised Customer Service technician clears any trapped suds from the level sensing assembly and verifies complete drainage and spin operation.
They must show youa test wash and spin cycle completing cleanly with no E4 error on the display.
In writingthe inspection of the water level and drain circuit, any original spare parts used, and the date of repair.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Verify detergent suitability and dosing for the programme
- Who:
- you.
- How:
- check that the detergent is specifically designed for automatic washing machines and is not overly foamy, and consult the programme table in the manual for the correct dose (rapid and delicate cycles require only a minimum dose).
- Result that matters:
- prevent excess suds from filling the tub, impeding the spin cycle and triggering E4/E04.
- If too much detergent or hand-wash soap was added:
- let the foam subside, then run a rinse and drain cycle with the extra rinse option and no detergent.
- If E4 appeared when using little or no detergent:
- proceed to clean the detergent drawer and drain filter and check the water level.
- Evidence to keep:
- brand/type of detergent and dose used when the E4 or E04 error occurred.

Clean the detergent drawer and run an empty rinse cycle
- Who:
- you.
- How:
- remove the detergent drawer, wash it thoroughly under running water to clear all detergent and fabric softener residues, refit the drawer, and run a wash or rinse cycle with no laundry or detergent added.
- Result that matters:
- flush leftover soap build-up from the dispenser line and drum.
- If the drawer had caked detergent residue and the empty cycle finishes without E4:
- reduce your detergent dose on future washes.
- If the drum still fills with too much water or foam returns:
- check the lower water filter and perform a 1-minute unplug reset.
- Evidence to keep:
- condition of the detergent drawer and whether an empty rinse cycle completed without E4.

Clean the lower water filter and unplug for 1 minute to reset
- Who:
- you.
- How:
- make sure there is no water left in the drum, open the bottom filter door, turn the filter knob counter-clockwise to remove it, rinse away lint and foreign bodies under running water, close the filter securely, then turn off and unplug the washer for 1 minute before restarting.
- Result that matters:
- ensure unobstructed drainage of suds and water and reset the control electronics.
- If debris was blocking the filter and the washer runs normally after the 1-minute reset:
- clean the filter regularly.
- If the filter is clean but too much water enters the drum or E4 recurs immediately:
- close the water supply tap and call an authorised technician.
- Evidence to keep:
- any debris found in the filter compartment and whether E4 cleared after the 1-minute unplug reset.

Authorised inspection of the water fill valve and level control
- Who:
- authorised Candy Customer Service technician.
- How:
- with the washing machine unplugged from the electrical supply and the water supply controlled, the technician inspects the water fill valve for overfilling and checks the water level sensing system.
- Result that matters:
- identify whether E4/E04 is caused by a defective fill valve letting too much water into the drum.
- If the fill valve fails to shut off properly and exceeds the maximum water level:
- the technician replaces it with an original Candy spare part.
- If the fill valve is sound but foam residue or a level sensing fault is present:
- the technician clears the pressure chamber or repairs the circuit.
- Evidence to keep:
- fill valve shut-off test result and verification of normal maximum water level in the drum.
Testing or replacing the internal fill valve involves 230 V mains wiring and pressurized water connections: work must be carried out by an authorised technician.

What it means
In the Candy Rapidò washing machine user manual (43032408) and Candy's official support FAQs, error code E4 or E04 (shown on models without a display as 4 flashes of every LED followed by a 5-second pause) indicates that there is too much foam and/or water inside the machine. In most cases it is triggered by using too much detergent or a product not designed for washing machines, though Candy notes it can also mean water has exceeded the normal maximum level. Seeing E4 or E04 does not by itself prove that the fill valve or any other part is defective.

Symptoms and causes
Probable causes · in order
- Excessive detergent dose or non-machine detergent usedCommon
Both the Rapidò manual and Candy's FAQ state that in most cases E4/E04 happens because too much detergent or an overly foamy detergent not meant for washing machines was used.
Evidence: Candy WM Rapidó user manual IT/DE/EN/ES/FR (43032408) · Candy UK frequently asked questions and appliance error codes
- Detergent build-up in the drawer or restricted drain filterPossible
Soap residue built up inside the detergent drawer or lint in the drain pump filter prevents excess suds and water from clearing during rinses and spin phases.
Evidence: Candy WM Rapidó user manual IT/DE/EN/ES/FR (43032408) · Candy UK frequently asked questions and appliance error codes
- Too much water entering the drum from a faulty fill valveLess common
Candy's official FAQ explains that E04 can also mean too much water enters the drum beyond the maximum normal operating level, usually caused by a defective fill valve.
