What Does the Hoover Washing Machine E03 Error Mean?

The Hoover E03 error code appears when the machine detects that water isn’t draining properly. This means that at the end of the wash cycle, the drum is still full of water instead of emptying out as it should.

What Happens When This E03 Error Occurs?

• The washing machine stops mid-cycle.
• The drum remains filled with water.
• The error code E03 flashes on the display.
• The machine won’t progress to the next cycle.

The good news is that this error is usually caused by a simple blockage in the drain system, which you can fix in a few easy steps.

Why Is My Hoover Washing Machine Not Draining?

If your Hoover washing machine is not draining, there are a few common reasons why:

1. Blocked Drain Pump

The drain pump removes water from the drum, but over time, debris like lint, coins, hairpins, and fabric fibres can clog it. If the pump is blocked, the water won’t drain properly.

2. Clogged Drain Hose

The drain hose carries wastewater from the washing machine to your home’s drainage system. If this hose is bent, twisted, or blocked, the water won’t be able to flow out.

3. Washing Machine Filter Blockage

The filter catches debris before it enters the drain pump. If it gets clogged, water won’t pass through properly, leading to drainage issues and the E03 error.

4. Faulty Drain Pump

In some cases, the drain pump itself may be broken. If the pump isn’t functioning, no amount of cleaning will fix the issue—it will need to be replaced.

How to Fix the Hoover Washing Machine E03 Error?

Follow these step-by-step solutions to fix the E03 error and get your machine draining properly again.

Step 1: Remove a Blockage from the Pump

The drain pump is one of the most common places for blockages to occur. Here’s how to check and clean it:

1. Unplug the washing machine to avoid electrical hazards.
2. Locate the drain pump filter—usually found at the bottom front of the machine behind a small panel.
3. Place a towel and a shallow container under the filter to catch any excess water.
4. Unscrew the filter cap and pull it out.
5. Remove any visible debris, such as lint, coins, or small objects.
6. Rinse the filter under running water and wipe away any dirt.
7. Reinsert the filter securely and close the panel.
8. Restart the machine to see if the issue is resolved.

Step 2: Inspect and Clear the Drain Hose

A clogged or kinked drain hose can prevent water from flowing out. Follow these steps to clear it:

1. Turn off the machine and unplug it.
2. Locate the drain hose at the back of the machine.
3. Check for kinks or bends—straighten the hose if necessary.
4. Disconnect the hose from the drainage pipe.
5. Run warm water through the hose to remove any blockages.
6. Reconnect the hose securely and test the machine.

Step 3: Clean the Washing Machine Filter

The filter plays a crucial role in trapping dirt and preventing blockages. If it’s clogged, your machine won’t drain properly.

• Locate the filter (usually at the front bottom of the washer).
• Open the filter cover and carefully unscrew the filter.
• Remove any trapped debris, such as lint, hair, or coins.
• Wash the filter under warm water.
• Replace it and secure it back in place.

Step 4: Reset the Hoover Washing Machine

If you’ve cleared the pump, hose, and filter but the E03 error still appears, try resetting the machine:

1. Turn off the washing machine and unplug it.
2. Wait 5–10 minutes to allow the system to reset.
3. Plug the machine back in and turn it on.
4. Run a short drain/spin cycle to check if the error is gone.

Hoover E03 Error but No Blockage – What to Do?

If you’ve checked for blockages and the E03 error still appears, the issue could be:

• A faulty drain pump—it may need replacement.
• A malfunctioning water level sensor—which isn’t detecting drainage properly.
• Electrical issues—such as faulty wiring or control board problems.

In this case, you may need to contact a professional repair service.

When Should You Call a Professional?

If you’ve tried all the DIY fixes and your Hoover washing machine is still not draining, it’s time to call an expert. Here are some signs you need professional help:

• The drain pump is broken and needs replacement.
• There’s a burning smell or unusual noises from the machine.
• Error codes keep appearing, even after resetting the washer.
