Bosch Dishwasher E06 — What It Means & How to Fix It

By Callum Griffin · Researched and verified against manufacturer and repair documentation · Reviewed June 2026

Bosch's E06 means the door-sensing circuit faulted — on most recent models the latch's reed switch cannot detect that the door is shut — so check the door closes firmly, reset once, then call a technician.

What this code means

E06 flags the door sensing circuit. On newer Bosch dishwashers that is the reed switch in the latch that confirms the door is properly closed; if it cannot see the door's magnet, the machine acts as though the door is open and refuses to run. On some older models the same code covered the optical “aqua sensor” that judges water clarity, and the two share a wiring branch.

What E06 points to varies by generation: a latch reed switch on recent units, an aqua (turbidity) sensor on some older ones. Check your model's manual to confirm which, since the repair differs.

Most likely causes

CauseHow likelyDIY-fixable?
Door latch or its reed switch is failing, so the closed door is not detected Common Partly — inspect only
Door is not fully engaging the latch (obstruction, misaligned rack, warped seal) Common Yes — clear and re-close
Wiring between the latch or sensor and the board is loose or broken Occasional No — technician job
Aqua/turbidity sensor fault on older models Less common No — technician job

What you can try yourself

  1. Open and firmly re-close the door, making sure no dish, rack corner, or detergent box is stopping it from latching fully.
  2. Check the latch area at the top of the door for food debris or a bent strike, and confirm the door closes with a solid click.
  3. Cut power at the breaker for two minutes and restore it, then start a cycle — if the door simply was not latching, E06 clears.
  4. If the code persists with the door closing normally, the reed switch or its wiring has failed; book a technician, as the repair runs into the door and control wiring.

When to call a technician

Typical professional repair cost: A door latch or switch replacement typically runs $130–$260 with labor; a sensor or wiring repair is usually in a similar range.

Frequently asked questions

Why does my Bosch say E06 when the door is closed?

On recent models E06 means the latch's reed switch cannot sense the door's magnet, so even a shut door reads as open. First make sure nothing is blocking a full latch; if it still shows, the switch or wiring needs replacing.

Is E06 always the door latch?

Mostly on newer machines, yes. On some older Bosch dishwashers the same code referred to the optical aqua sensor that checks water clarity, so check your model's manual to be sure which part applies to yours.

Can I fix E06 myself?

You can rule out the easy cause — a door that is not latching because something is in the way — and try a power reset. Replacing a failed latch switch or repairing the wiring is a technician job.
