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
- Remove the bottom rack and clean the filter/sump of food.
- Check the drain hose for kinks and clogs at the high loop.
- If a disposal was just installed, confirm the knockout plug was removed.
⚠️ Doable — know the risk
- Drain pump replacement — moderate; cut power at the breaker and shut the water off.
🛑 Call a pro — don't touch this
- A leak reaching the wiring/control under the tub.
