Seeing E14 on a Bertazzoni dishwasher usually points to a control board issue. Think of the board as the dishwasher’s “brain”: it coordinates water intake, heating, spray cycles, and drain timing. When the board glitches or fails, the machine can’t follow its program and throws E14 to protect itself.
What typically triggers E14
Most cases trace back to one of a few scenarios: a brief power surge or outage, a shorted wire or connector in the harness, a failed component on the board (relay, capacitor, burnt trace), or physical moisture/heat damage inside the control compartment. Sometimes E14 appears intermittently at first—missed starts, random resets, lights flashing—then becomes persistent.
What you’ll notice
- Cycle won’t start or stops mid-way
- Panel responds, but nothing “happens” inside (no fill, no spray)
- Odd behavior after a storm, outage, or when other heavy appliances kick on
Quick checks before you call a tech
These steps are safe for most homeowners and can rule out simple causes:
- Power and breaker: Make sure the plug is seated, the outlet is live, and the dishwasher is on a dedicated circuit. Flip the breaker off for 2 minutes, then back on to hard-reset the control.
- Outlet health: If it’s on a GFCI/AFCI outlet, press RESET. Avoid extension cords or power strips.
- Door latch: Open/close firmly; a misaligned latch can mimic a control fault.
- Signs of moisture: If the control area recently got damp (leaks, steam), give it time to dry and try again.
If E14 returns after a proper reset and these basics, the board likely needs professional diagnosis. Continuing to cycle power repeatedly won’t fix a failing component and can make things worse.
Why a technician is worth it
A pro can run live voltage tests, check harness continuity, inspect the inlet valve, thermistor, and pumps that the board commands, and confirm the board is the actual culprit—not just the messenger. If the board is bad, they’ll match the correct part revision, handle ESD-safe installation, and update any seals or gaskets that help keep moisture away from electronics.
Can the board be repaired, or is replacement the only path?
- Minor issues (burnt solder joints, relay) can sometimes be repaired by a qualified electronics tech, but this isn’t always cost-effective or reliable long-term.
- Replacement is the common route. Prices vary by model and region, and labor tends to be the bigger portion of the bill. Ask for a diagnosis quote first.
How to prevent a repeat
Keep electronics happier and E14 rarer with a few habits:
- Use a surge protector rated for appliances (or a whole-home surge device).
- Avoid back-to-back heavy loads on the same circuit (ovens, space heaters).
- Fix leaks and door-seal issues promptly—moisture and boards don’t mix.
- If outages are common, wait for stable power before starting a long cycle.
E14 = control board fault most of the time. Do a clean power reset, verify the outlet and breaker, check the latch, and look for moisture. If the code persists, book a technician for proper testing and, if needed, a board replacement. That gets you out of the guesswork loop and back to quiet, reliable cycles.
