Bosch Dishwasher E15 Error: Leak Tray Reset Guide

Bosch dishwasher E15 means water reached the base leak tray and opened the float safety switch. Condensation, a loose clamp, or oversuds can cause E15—not always a catastrophic tub crack. Dry the base carefully, then find why water got there.

Clear E15 safely

1. Kill power and water supply. Pull the unit carefully if you need base access.
2. Absorb all water from the base pan; leave the float switch dry and free to move.
3. Check inlet and drain hose clamps for seepage; replace brittle hoses.
4. Use proper dishwasher detergent—hand soap foam triggers phantom leaks.
5. Restore power and run an empty short cycle while watching the base.

If E15 returns

Circulation pump seals, door gasket corners, or a cracked sump need parts work. Do not tape over the float—that disables a safety.

Quick FAQ

Can I tilt the dishwasher to drain the tray?

Slight tilting helps some models; protect floor and hoses first.

E15 after installer visit?

Re-check drain hose height and knockout plugs.

Prevention tips

Use measured dishwasher detergent only—suds overflow is a classic E15 false leak. Replace door gaskets that weep at the bottom corners. When sliding the unit, support hoses so fittings do not drip into the base tray. After clearing E15, watch the next two cycles with a flashlight along the base.

Tip: Place a towel under the front edge before sliding the unit out—old drips always appear.
