What the E14 error code means

The E14 error on a Bosch dishwasher usually indicates a flow meter failure or there’s a problem with water entering the machine.

The flow meter measures the amount of water entering the dishwasher. If it malfunctions, it can trigger the E14 error. This can happen due to wear and tear over time or electronic faults within the flow meter.

Problems with the water supply to the dishwasher can also trigger the E14 code. This might include a clogged water inlet valve, kinked or damaged water supply lines, or insufficient water pressure.

Safety precautions

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind:

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by eliminating any risk of electric shock.
• Turn off the water supply at the outlet before beginning repairs. Keep towels ready to catch any residual water in the system when removing parts.
• If the appliance has recently been used, give it plenty of time to cool down before working on it.
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Always take photos or make a note of wiring terminals or other connections before disconnecting them to make reassembly easier.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.

How to troubleshoot an E14 error code

Follow these steps to clear the E14 error from your Bosch dishwasher.

Step 1: Inspect the water supply

Make sure the water supply valve leading to the dishwasher is fully open. Inspect the water supply line for any kinks, blockages, or damage. Replace any damaged lines, straighten out kinks and remove any blockages that you find.

If the water supply valve and line look good, move on to the next step.

Step 2: Check the water pressure

Use a pressure gauge to check if the water pressure in your home is sufficient. If it’s low, contact a professional plumber to fix the issue.

If the water pressure is good, move on to the next step.

Step 3: Inspect the flow meter

1. Find the flow meter in your dishwasher. It’s typically near the water inlet valve or on the side of the dishwasher.
2. Look over the flow meter for any visible damage or signs of wear. If you find any damage, replace it with a new one.

If the flow meter looks good, continue to the next step.

Step 4: Check the water inlet valve

1. Disconnect the dishwasher from the power source.
2. Shut off the water supply to the dishwasher.
3. Find the water inlet valve, which is typically located at the back or side of the dishwasher. Consult your dishwasher’s service manual if you need help finding its exact location. You may need to remove the dishwasher’s outer panel or access cover to reach the valve.

LIVE VOLTAGE WARNING: For this test, the dishwasher needs to be plugged in and powered on. Please be very careful to protect yourself from electric shock, which has the potential to cause serious injuries. Don’t ever test live voltage if you’re uncomfortable using a multimeter.

Set the multimeter to the voltage setting and use the probes to test at the terminals. You should see 120 VAC when the dishwasher is powered on, a cycle is started, and the valve is opened. If you see 120 VAC here and no water comes through, you’ll need to replace the water inlet valve. If you don’t see 120 VAC, continue to the next step.

Step 5: Check the float switch

1. Unplug the dishwasher from the power outlet.
2. Find the float assembly, which is typically located at the bottom of the dishwasher tub. You may need to remove the lower rack or access panel to reach it.
3. Gently move the float up and down and make sure it moves without sticking.
4. Set a multimeter to the continuity or ((( mode.
5. Touch the multimeter probes to the terminals of the float switch.
6. Check the meter reading. When the float is in the down position (no water), the multimeter should show continuity. When you slowly raise the float, the multimeter reading should change to an open circuit (OL).
7. Inspect the float assembly and surrounding areas for any signs of water leaks that could be causing the float to malfunction. Fix any leaky areas that you find.

If the float is stuck or the float switch tested bad, you’ll need to replace the float assembly.
