- Leak Into Base
- Float Switch Tripped
The Tools to Test + Fix With
You don't need a shop full of tools — you need these. The multimeter is the one that pays for itself the first time it stops you buying the wrong part on a fault code.

Test a suspect part for continuity BEFORE you buy — the single best way to avoid replacing the wrong thing on a fault code.

🔎 On Amazon →The Fix — Free Checks First, Then the Part
Work top-down: the free checks before you spend a dime, and test to confirm the part is actually bad before you buy. When it is a part, you get both options — the genuine OEM part sourced through us and shipped to your door, or a budget aftermarket part on Amazon. Your call.
No part — drain the base pan & dry the float
Tilt the dishwasher back ~45° to drain water from the base, or soak it out with a towel so the foam float drops. Clears the E15 in most cases.
✅ No part needed — try this firstFind & fix the leak source
If E15 returns fast, water is still getting into the base — check the door seal, hose clamps, and the drain hose/sump for the leak, then replace the failed part.

Safe to Try · Know the Risk · Call a Pro
General guidance, not professional advice. Always unplug the appliance (or shut off the gas/water) before you check anything. If it feels beyond you, that's exactly when to get a pro.
✅ Safe to try yourself
- Turn off the dishwasher and tilt it back to drain the base pan (towel underneath).
- Dry the base so the foam anti-flood float drops.
- Restart — if E15 clears and stays gone, it was a one-time spill.
⚠️ Doable — know the risk
- Tracing and replacing a leaking seal/hose — moderate; power and water off, some disassembly.
🛑 Call a pro — don't touch this
- A leak you can't locate, or water reaching the wiring/control.
The Honest Call
Often free — an E15 is frequently just a drained-pan reset. Only a real, recurring leak means a part ($15–70), still far under a new machine.
