E18
Balay E18 on a dishwasher: not enough water coming in
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
The dishwasher is not getting water as it should. Balay lists four causes you can check: kinked hose, closed tap, scaled tap or blocked inlet filter. Start with the tap and the hose.
Safety first
Stop and check this first
- Close the tap before disconnecting the hose to clean the filter, or water will come out under pressure.
Safe checks you can perform
- Dishwasher tap fully open
- Inlet hose free of kinks
- Tap flow
- Water inlet filter clean
Leave these tasks to a qualified professional
- Do not attempt this professional task: Check the inlet valve
- Do not attempt this professional task: Fill test after the repair
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.
Check the inlet valve
What they doThe technician measures the inlet valve coil and checks whether it opens when the board powers it.
They must show youthe measured value against the manufacturer's specification.
In writingthe result and the part replaced.
Fill test after the repair
What they doThe technician runs a programme and checks that the appliance fills without the code.
They must show youa complete fill without error.
In writingwhat was replaced or adjusted and why.
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.
Dishwasher tap fully open
- Who:
- you.
- How:
- open the valve that feeds the dishwasher all the way and start the programme again.
- Result that matters:
- whether the appliance begins to fill.
- If it fills and the code clears:
- the tap was closed or half open.
- If the code remains:
- check the hose.
- Evidence to keep:
- photo of the valve position.

Inlet hose free of kinks
- Who:
- you, with the appliance unplugged.
- How:
- follow the hose from the tap to the appliance and lay it without folds or crushing.
- Result that matters:
- that water can flow freely.
- If it was kinked:
- straighten it and test again.
- If it is laid correctly:
- check the tap flow.
- Evidence to keep:
- photo of the hose before and after.

Tap flow
- Who:
- you.
- How:
- with the hose disconnected from the tap and a bucket, open the tap for one minute and measure the water collected with a graduated container.
- Result that matters:
- whether it reaches 10 litres per minute, as Balay states.
- If it delivers less:
- the tap may be scaled; it must be cleaned or replaced (a plumber if you are unsure).
- If it delivers 10 litres per minute or more:
- check the inlet filter.
- Evidence to keep:
- litres collected in one minute.

Water inlet filter clean
- Who:
- you, with the tap closed and the appliance unplugged.
- How:
- disconnect the hose and clean the filter following your model's manual or Balay's video.
- Result that matters:
- that the filter is free of dirt and scale.
- If it was blocked and the code clears after cleaning:
- that was the cause.
- If the filter was clean and everything above is correct:
- call Balay's official service.
- Evidence to keep:
- photo of the filter before and after.

What it means
Balay links E18 to water intake problems: a kinked inlet hose, a closed tap, a scaled tap (it asks you to check the flow reaches 10 litres per minute) or a blocked water inlet filter. These are all installation checks. If the tap, hose and filter are fine and the code remains, water intake inside the appliance (valve or its control) needs technical inspection: the code alone does not tell them apart.
Warnings and stop conditions
- Loweditorial warning
Close the tap before disconnecting the hose to clean the filter, or water will come out under pressure.

Symptoms and causes
Probable causes · in order
- Tap closed or half openCommon
The simplest cause. It is confirmed if the programme starts once the tap is fully open.
Evidence: Balay España códigos de error del lavavajillas
- Kinked inlet hoseCommon
Pushing the appliance into the cabinet can pinch the hose. You see it after pulling the appliance out just enough.
Evidence: Balay España códigos de error del lavavajillas
- Scaled tap with low flowPossible
The tap is open but delivers little water. Balay asks you to check it reaches 10 litres per minute.
Evidence: Balay España códigos de error del lavavajillas
- Blocked inlet filterPossible
The filter at the hose connection traps dirt or scale. You see it when you disconnect the hose with the tap closed.
