When a Bertazzoni dishwasher throws an E02, it’s complaining about the water inlet valve not closing as it should. In plain terms: the machine isn’t managing water flow correctly. That can keep the tub from filling, leave cycles stuck at the start, or create weird behavior later in the wash (like poor cleaning or awkward pauses).
You’ll usually notice one of a few patterns: the cycle won’t start filling at all, it fills too little and sounds “spray-starved,” or it seems to fill and then stalls because the control can’t confirm proper water level.
Quick checks (2–3 minutes)
- Make sure the water supply tap is fully open and household water pressure is normal.
- Inspect the inlet hose behind the machine for sharp bends, kinks, or visible damage.
- Look for obvious leaks around the bottom front/kick area after a short fill attempt.
If those basics are fine, move on to a slightly deeper look.
A smarter way to troubleshoot E02
- Power and safety first
Turn the dishwasher off and unplug it (or switch off the breaker). You’ll be near wiring and valves—treat it like real electrical work. - Confirm water is available
Open another nearby faucet. Weak flow at the sink can mean low building pressure or a partially closed shutoff. Fix the water supply before blaming the dishwasher. - Check the inlet valve area
The inlet valve sits low on the unit where the hose connects. With power off, feel around for dampness. Any persistent moisture suggests the valve isn’t sealing fully. - Rule out a kinked or clogged line
Disconnect the inlet hose at the valve end (have a towel ready). Inspect the tiny mesh screen in the valve’s port—sediment or scale here can starve the machine. Rinse gently; don’t poke the screen with sharp tools. - Listen for the valve during a test fill
Restore power, start a quick cycle, and listen: a healthy valve makes a soft hum when energized, then you’ll hear water entering. A loud buzz with no water flow points to a clogged screen, closed tap, or failed valve. Silence when it should fill can also mean a control/relay issue. - Consider the sensor side of the story
If the tub does fill but the control still throws E02, the board may think the valve isn’t behaving (even if water arrived). That can be a failing valve coil drawing odd current, or a control board misreading things. At this point, pro diagnostics are wise.
Most common causes (from most to least likely)
- Debris or limescale caught in the inlet screen or valve seat
- Weak or failed inlet valve (coil or internal seal no longer reliable)
- Kinked/damaged inlet hose restricting flow
- Low/unstable household water pressure
- Control board or wiring fault (less common, but possible)
Can you fix E02 yourself?
Often, yes—especially when it’s supply-related or a clogged screen:
- Straighten/replace a kinked hose.
- Clean the mesh screen carefully and re-seat the hose.
- Verify the shutoff is fully open and pressure is normal.
If the error persists after a clean screen and known-good water supply, the inlet valve itself is the usual culprit and typically needs replacement. Swapping a valve is straightforward for someone comfortable with basic tools and safe electrical practices, but if you’re unsure—or if you suspect a control board issue—call a qualified technician. That avoids water damage or an electrical mishap and ensures the machine is retested for leaks, proper fill time, and error-free cycles.
E02 means the dishwasher isn’t happy with how the inlet valve is controlling water. Start with simple supply checks, clean the valve screen, and make sure the hose isn’t kinked. If that doesn’t clear it, plan on a new inlet valve or a professional diagnosis to rule out the control board. This approach saves time, avoids guesswork, and gets you back to quiet, reliable washes.
