I30
Zanussi i30 on a dishwasher: water detected in the base
Risk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
On a Zanussi dishwasher, i30 (or three beeps) means the anti-flood device has acted, often because of water in the base. Close the dishwasher tap now, unplug it without standing in water and do not use it until checked.
Safety first
Stop and check this first
- Water and electricity: with water on the floor or in the base, do not touch the plug with wet hands or feet or tilt the appliance to empty it; cut the power at the consumer unit.
- Turn off the dishwasher's water supply to avoid any risk of flooding, as Zanussi says.
Safe checks you can perform
- Tap closed and power off
- Load, arms, filters and seal
- Test after a night off

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.
Find the leak in the base
What they doWith the appliance disconnected from mains and water, the engineer opens the base, checks for water and follows the trail to the leaking hose, seal or joint.
They must show youthe water in the base and the leak point found, with a photo.
In writingthe leak source, what was repaired or replaced with its part number and why.
Drying and test programme
What they doThe engineer dries the base, lets the anti-flood device reset and runs a full programme watching for leaks.
They must show youa dry base and the programme finished without i30.
In writingthe programme tested, the result and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
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.
Tap closed and power off
- Who:
- you, no tools.
- How:
- close the dishwasher tap, as Zanussi asks to avoid flooding. Unplug it if the plug and the floor are dry; if not, switch off its circuit at the consumer unit.
- Result that matters:
- whether the pump stops and no more water comes out.
- If water keeps coming with the tap closed:
- it comes from the household plumbing; call a plumber.
- If it stops:
- keep the tap closed and carry on with the checks.
- Evidence to keep:
- a photo of the code, the floor and the closed tap.

Load, arms, filters and seal
- Who:
- you, with the appliance unplugged.
- How:
- remove large items that could block the arms or deflect the jet, turn the arms by hand, clean filters, arms and sump, and look at the door seal. Look for foam in the tub too.
- Result that matters:
- whether something blocked an arm, there was foam, or the seal is dirty or damaged.
- If there was foam or an item blocking an arm:
- correct it and leave the appliance off overnight with the tap closed.
- If the seal is damaged:
- do not use it; tell the engineer.
- Evidence to keep:
- a photo of the load, the seal and the foam if any.

Test after a night off
- Who:
- you to watch; an engineer if it repeats.
- How:
- after a night unplugged with the tap closed, plug in, open the water and run a programme while keeping an eye on it.
- Result that matters:
- whether the programme finishes without i30.
- If it finishes with no alert:
- foam or loading was the likely cause; watch the next washes.
- If i30 returns:
- close the tap and book the repair; the base is still getting water from an internal leak.
- Evidence to keep:
- a photo of the code and when it appeared.

What it means
Zanussi links i30 to water collecting in the base of the appliance: the anti-flood device acts and the drain pump may keep running. It can be an internal leak, but Zanussi also names excess foam and a spray arm blocked by a large item that deflects water onto the door seal. The alert may clear after a night unplugged, but if the leak remains it returns. The code does not locate the leak; that needs the appliance opened.

Symptoms and causes
Probable causes · in order
- Internal leakPossible
Zanussi says an authorised technician is then needed. Fits if i30 returns with loading and foam ruled out.
Evidence: Dishwasher displays error code i30 | Zanussi
- Excess foamPossible
Fits if you see foam in the tub, for example after using an unsuitable detergent. Zanussi says to leave it off overnight so it disperses.
Evidence: Dishwasher displays error code i30 | Zanussi
- Spray arm blocked or large itemPossible
A tray or large item stopping the arm sends the jet at one spot on the seal and causes the leak.
Evidence: Dishwasher displays error code i30 | Zanussi
- Dirty or damaged door seal, or appliance not levelPossible
Zanussi asks you to check the seal, the installation and levelling. Told apart by looking at the seal and the appliance.
