Bosch Dishwasher E17: How It Ruins Your Washes Completely

So, you just started your dishwasher, but instead of the typical gentle swoosh of water, you’re greeted with an odd buzzing sound and an E17 error code. 

What’s happening? Don’t worry – there’s no electrical meltdown going on in there! 

What does E17 mean on Bosch dishwasher, then? 

Bosch Dishwasher E17 Error Code means a problem with water flow. It can be due to an inconsistent water supply, broken float switch, broken water level sensor, or debris in the float chamber and filters. Cleaning and replacing these parts will fix the error.

Don’t worry though – no need for a technician yet! I’ll tell you about this error and how to clear it quickly. Try the fixes I give ASAP to avoid eating on dirty dishes!

When Bosch Dishwasher E17 Error Occurs

So,  this E17 error is the opposite of E16. Rather than popping up because of overfilling, it appears the dishwasher fails to get filled with water at all. 

It can ruin your wash quality, as you need water for the machine to actually clean.

Here are the main reasons why your water flow isn’t working right:

1. Water Supply Issues

The error can be attributed to:

• Water Supply Valve Fault: The inlet valve may be faulty or clogged, hindering water flow.

• Low Water Pressure: Insufficient main supply pressure leads to inadequate water filling.

• Kinked or Damaged Water Line: A bent or damaged water line obstructs water flow, triggering the E17 error.

2. Faulty Float Switch

The float, responsible for detecting water levels, can get stuck in the bottom or be in the wrong position, causing the dishwasher to think it’s already full and prevent water from entering.

3. Clogged Filters

Clogged filters can prevent water from entering the dishwasher in different ways:

• Blocked Inlet Filter: The filter that screens out debris in the water might be clogged, preventing water from entering.

• Clogged Spray Arms: If the dishwasher’s spray arms are clogged, water won’t distribute evenly, leading to a shortage of water inside.

4. Defective Water Level Sensor

A malfunctioning water level sensor can cause False Water Level Indication, leading the dishwasher to stop filling water prematurely due to inaccurate feedback to the control board.

5. Dirty Bottom And Float Chamber

When these areas are dirty, they can block water flow or misinterpret water levels, resulting in the dishwasher not filling with water correctly and triggering the E17 error. 

How To Fix E17 Error In Bosch Dishwasher

Alright, let’s fix that E17 error on your Bosch dishwasher together! Follow these simple step-by-step fixes, and get it sorted in no time.

Fix 1: Check The Water Supply System

Let’s start with a simple fix, checking if your water supply is actually working. 

It’s a common culprit for this error, so let’s see if we can get things flowing smoothly again.

1. Turn off the dishwasher and unplug it.
2. Locate the water supply valve, usually under the sink or behind the dishwasher.
3. Make sure the water supply valve is fully open.
4. Check the water supply hose for any kinks, bends, or damage.
5. Ensure the main water supply to your house provides sufficient water pressure.

Fix 2: Clean Filters

You can also give the filters a simple clean in case they have something that’s blocking the water flow, do so by the following steps: 

1. Open the dishwasher door and slide out the lower dish rack.
2. Find the inlet filter at the bottom of the dishwasher and clean it by rinsing it under running water.
3. Inspect the spray arms for any clogs and remove any obstructions.
4. If your dishwasher has a separate drain filter, check and clean it as well.

Fix 3: Clean the Bottom and Float Chamber

That didn’t work? Well then, you’ll need to clean the dishwasher’s bottom and the float chamber. 

Sometimes, a little debris can cause big issues, but with a bit of cleaning, you can get that dishwasher back to its sparkling performance. 

Here’s how you can do so:

1. Turn off the dishwasher and empty it.
2. Remove the bottom rack to access the bottom area.
3. Thoroughly clean the bottom of the dishwasher to remove dirt and debris.
4. Locate the float chamber (a small, usually round or dome-shaped part) at the center of the bottom area.
5. Check the plastic or styrofoam float inside the float chamber for free movement.
6. Clean the float chamber if any debris is present.
7. Put the bottom rack back in place.

Fix 4: Take Care of The Float Switch

This fix is the most complicated, besides replacing the water inlet valve. 

Start by checking if the float switch needs a replacement. 

To inspect the float switch and fix it, follow these steps:

1. Turn off the dishwasher’s power and disconnect the water supply and electricity.
2. Locate the float switch near the float chamber beneath the dishwasher’s tub.
3. Check for visible damage or cracks on the float switch.
4. Gently lift the float in the float chamber and ensure it moves smoothly without resistance. Listen for a clicking sound.
5. Test the float switch with a multimeter on continuity setting. There should be continuity when the float is raised and none when lowered.
6. If the float switch shows continuity as described, it’s likely not the cause of the E17 error. If not, proceed to replace the float switch.
7. Disconnect wires from the old float switch.
8. Remove the old float switch using pliers and the new float switch, securing it with screws or clips.
9. Reconnect the wires to the new float switch in the original positions.
10. Reassemble the removed parts.
11. Turn on the dishwasher’s power and water supply.
12. Test the dishwasher by running a short cycle to ensure the new float switch works.

Following these steps, you can easily check and replace the float switch, resolving the E17 error and ensuring proper dishwasher functionality.

Fix 5: Inspect And Potentially Replace The Water Inlet Valve

Like the float switch, you’ll need to check this one first, so start with that, then move on to fixing:

1. Turn off the dishwasher power and disconnect the water and power supply.
2. Locate the water inlet valve at the bottom of the dishwasher.
3. Check for leaks or visible damage.
4. Briefly turn on the water supply with the dishwasher off and the hose disconnected.
5. If there is continuous water flow or no flow, the valve may be faulty.
6. Test the valve’s electrical connections with a multimeter for continuity.
7. If the valve shows no leaks or damage and stops water flow when disconnected, it’s likely not causing the E17 error.
8. If there are water flow or electrical problems, move on to replacing the valve.
9. To replace the valve, remove the old one hidden behind a cover at the bottom.
10. Carefully disconnect the water supply hose using pliers, remove screws or clips holding the old valve, and detach wires connected to the old valve.
11. Install the new valve in the same spot, securing it with screws or clips.
12. Attach wires to the new valve in their original positions.
13. Reconnect the water supply hose and tighten it with pliers.
14. Turn on the water supply and check for leaks.
15. Replace the removed covers or parts.
16. Turn on the dishwasher power and water supply.
17. Run a full cycle to ensure the E17 error is resolved.

Fix 6: Check And Replace The Water Level Sensor

Here’s what you need to do:

1. Turn off the dishwasher and unplug it.
2. Remove the front or access panel to access the water level sensor.
3. Locate the water level sensor near the float assembly under the dishwasher tub.
4. Check the sensor’s wiring and connectors for damage or looseness.
5. Test the sensor’s continuity using a multimeter set to “ohms” or “resistance” mode.
6. If the sensor shows continuity and no visible damage, it’s likely functioning correctly and doesn’t need replacement.
7. If there’s no continuity or visible damage, consider replacing the water level sensor.
8. To replace the sensor, disconnect the wires from the old one.
9. Remove the old water level sensor from its mounting location.
10. Install the new water level sensor in the same position.
11. Reconnect the wires securely to the new sensor.
12. Reassemble the panels removed earlier.
13. Plug the dishwasher back in.
14. Run a test cycle to ensure the E17 error is resolved and the new water level sensor functions correctly.
