Clogged Drain Hose or Drain Pump

Faulty Water Inlet Valve
A faulty water inlet valve can prevent water from entering the dishwasher, causing the red light to blink.

Overfilled Dishwasher
Overfilling your dishwasher can cause water to leak out and trigger the red light to blink.
- Ensure that you do not overload the dishwasher with too many dishes or utensils.
