Understanding and Repairing the Ariston Dishwasher F02 Error Code
If you have been getting an “F02” error code flashing on your Ariston dishwasher, well, you are not alone. While this might appear a little scaring, don’t worry; we’re here to help you diagnose the problem and get this dishwasher back doing what it does best.
Let’s break down what F02 means, why it would come on, and how you can fix this trouble code. The F02 error code describes an issue with the water supply. That is correct; your dishwasher is not getting the right amount of water to function. No proper water flow is no good because the machine can’t perform accordingly. Here’s a summary.
A number of these types of faults can be due to a few common causes-and thankfully, many of them are pretty easy to discover and resolve.

Why am I getting the F02 code?
Here are a few possible reasons why your Ariston dishwasher may give you an F02 error code:
- Kinked/Blocked Hose: The water inlet hose to the dishwasher may be kinked, twisted, or blocked somehow and restrict the flow of water.
- Clogged Water Filter: Over time, food particles and other particles build up in the filter and eventually block it.
- Low Water Pressure: If the water pressure in your house is abnormally low, your dishwasher may have difficulty filling as it should.
- Valve Issues: The water inlet valve that regulates the water coming into your dishwasher may be faulty or clogged.
How to Fix the F02 Error Code
Now that you have an idea of what could be causing this, it’s time to get your hands dirty to have your dishwasher up and running. Here’s how you can fix the issue in a couple of steps:
1. Check the Water Supply
Ensure that the water supply to your dishwasher is turned on and works well. Also, make sure the faucet from which the connection to the dishwasher is made is not off.
2. Water Hose Check
This should be checked for bends, kinks, or discoloration. If it’s only bent, straighten out the bend; however, if it looks damaged, then replacement might be a good idea.
3. Water Filter Clean
Other possible culprit would be the filter of the water. Find it in your dishwasher and clean the clogging dirt from it. This should get the job done in an instant; however, soak it in soapy, warm water before re-rinsing for difficult ones.
4. Water Pressure
Check that your home’s water pressure is within the range required by the dishwasher. If it consistently appears to be too low, you may want to contact either your water supplier or a plumber.
5. Check the Water Inlet Valve
The inlet valve may be clogged or defective. You can try cleaning minor blockages, but a faulty inlet valve will have to be replaced. This may involve professional help if you are not comfortable dealing with internal parts of the dishwasher.
When to Call a Professional
If you’ve run through the above steps and the F02 code is still popping up, it might be time to call in the pros. Technicians have the expertise and tools to resolve more complex issues, making sure your dishwasher gets the care it needs.

Pro Tips to Avoid Future Errors
- Routine Maintenance: Regular cleaning of the water filter and checking up on the water hose to prevent blockages.
- Keeping the Hose Straight: The water inlet hose should not be twisted or folded during installation or use.
- Use the Right Detergent: Only use dishwasher-approved detergents for better maintenance of the system.
- Monitor the Water Pressure: Keep a keen eye on the water pressure in your house and take prompt action if you feel any fluctuations.
