Important Tips for Bosch Models

  • Bosch models may display error code E14 on overfilling/underfilling issues indicating fill valve or sensor faults

Possible Causes

Faulty water inlet valve allowing continuous water flow

How to Identify: Ice maker overfills even when bin is full; water continues to flow into ice maker; symptoms similar to E14 error codes on some Bosch models

Part: Water inlet valve

Ice level detection failure (mechanical arm or sensor)

How to Identify: Ice maker does not stop producing ice when bin is full; feeler arm stuck or blocked or optical sensor blocked or dirty

Part: Feeler arm or optical sensor/ice level sensor

Low household water pressure

How to Identify: Slow water fill at dispenser too; water pressure below recommended (often <20 psi causing improper valve closing leading to overflow

Part: Water supply line/pressure

Misaligned or obstructed ice bucket/bin

How to Identify: Ice overflow occurs despite proper ice level; bin not seated correctly under ice maker sensor or obstructed causing false readings

Part: Ice bucket and installation alignment

Damaged ice maker assembly (mechanical failure)

How to Identify: Other causes ruled out; internal ice maker parts cracked or worn causing uncontrolled fill or dispensing

Part: Ice maker assembly

DIY Solutions

Check and free the ice level shut‑off arm or sensor

Easy 10-20 minutes
Tools Needed: none or soft cloth

  2. Clear any ice cubes blocking the arm/sensor and ensure it moves freely
  3. Gently clean sensor surfaces and reposition ice bin properly
⚠️ Safety First: Ensure power is off if the sensor requires handling; avoid sharp tools that could damage sensor/arm

Inspect and clean ice maker fill tube and inlet screen

Moderate 15-30 minutes
Tools Needed: towel, small brush, bowl
  1. Unplug refrigerator and shut off water supply

  3. Clean debris from screen and tube; flush with warm water if partially frozen
  4. Reconnect and restore power/water, test cycle
⚠️ Safety First: Turn off power and water to prevent leaks or electrical hazards

Check water pressure and adjust if low

Moderate 30-60 minutes (may require plumber)
Tools Needed: water pressure gauge
  1. Attach gauge to water supply and measure pressure
  2. If below ~20 psi, adjust household supply or install booster
  3. Replace clogged water filter if present
⚠️ Safety First: Professional help recommended for modifying household water pressure
