The Bosch dishwasher E24 error code indicates there is an issue with water drainage from the dishwasher, typically caused by a blocked or clogged filter. This error can prevent the dishwasher from operating properly through a full cycle and getting dishes clean. While frustrating, the E24 error code can often be resolved through some simple troubleshooting and maintenance steps. With a little time and effort, you can likely get your Bosch dishwasher draining properly once again.

Introduction

Bosch dishwashers are known for their quiet operation and cleaning performance. However, like any appliance, they can encounter issues from time to time. The E24 error code on Bosch dishwashers indicates a drainage problem, usually involving a clogged or blocked filter preventing water from properly draining out of the dishwasher.

This article will provide a comprehensive overview of troubleshooting the E24 error code, looking at the most common causes and solutions. Key topics will include:

• What triggers the E24 error code
• Step-by-step methods to check common causes like the drain hose, drain pump, filters, and connections
• Tips for unclogging blocked drains and filters
• Preventative maintenance to avoid E24 errors
• When to call for professional service

Properly troubleshooting the E24 error is important for restoring normal operation of your Bosch dishwasher. With some basic DIY techniques, you can often resolve E24 errors yourself without the hassle and expense of a service call. Let’s start by looking at what causes the dreaded E24 code.

What Triggers the E24 Error Code?

The E24 error code indicates that water is unable to properly drain out of the dishwasher after a wash cycle completes. There are a few common causes:

Clogged or Blocked Drain Filter – The drain filter is intended to catch food debris and prevent it from clogging dishwasher components. However, over time, food particles, grease, and limescale can build up in this filter and impede drainage. The filter needs periodic cleaning.

Blocked Drain Hose – If the drain hose that removes water from the dishwasher becomes kinked, clogged, or blocked, it can trigger the E24 code. Food bits, grease, and debris can cause blockages.

Faulty Drain Pump – The drain pump is responsible for pumping water out of the dishwasher tub. If this pump fails or malfunctions, water will not drain properly, signaling the E24 error.

Blocked Siphon Connection – This curved connector links the drain pump to the drain hose. Blockages here can impede water drainage.

Problem with Water Level Sensor – The dishwasher relies on a water level sensor to monitor drainage. If it malfunctions, it may incorrectly signal an E24 code.

In most cases, the E24 error is caused by a fairly straightforward drainage issue. Let’s look at the steps to troubleshoot and resolve it.

Step-by-Step Troubleshooting for E24 Errors

When your Bosch dishwasher displays the E24 code, there are a sequence of troubleshooting steps you can follow to identify and fix the problem:

1. Check Drain Hose – The drain hose routes water from the dishwasher to the sink drain or garbage disposal. Check along the entire length of the hose for kinks, bends, or blockages that prevent proper water flow. The hose should have a constant downward slope and no sharp bends. Use a wire coat hanger to clear any debris clogs.

2. Clean Drain Filter – The drain filter is typically located along the bottom of the dishwasher tub. Remove it and rinse under warm water to remove any accumulated food particles or debris. Refer to your owner’s manual for the proper filter removal and cleaning method for your model. Reinstall the filter once cleaned.

3. Check Siphon Connection – The siphon is a curved connector between the pump and drain hose. Unclip this connection and check both openings for blockages. Run water through to flush out any debris. Reconnect once clear.

4. Drain Pump Test – You can verify the drain pump is operational by pouring a few cups of water into the dishwasher tub. Turn on the dishwasher and listen closely for the pump to turn on and drain the tub. If it doesn’t drain, the pump may need replaced.

5. Clean Dishwasher Interior – Run a dishwasher cleaner like Affresh or LemiShine once per month to remove grease and limescale buildup. This can help prevent drainage issues.

6. Confirm Proper Detergent Use – Only use dishwasher-specific detergents. Hand washing detergents can create excess suds that clog pumps and drains. Don’t overfill detergent dispensers.

7. Check Water Level Sensor – The sensor monitors tub drainage under the filters. Clean with rubbing alcohol and check connections. Replace if faulty.

8.Electronics Testing – If other parts check out, a technician can check control board operation and electrical components related to the drain system.

Following this sequence can help pinpoint the problematic component. In many cases, the cause is a simple clog requiring basic cleaning and maintenance to remedy.

Unclogging Blocked Drains

If inspection reveals a clogged drain hose, drain pump filter housing, or siphon connection, some hands-on unclogging steps may be needed. Here are some tips:

• Use a wire coat hanger or zip tie to loosen and extract debris clogs from hoses.
• Flush hoses and drains with hot water to dissolve grease deposits. Use caution to avoid burns.
• For stubborn clogs, carefully use a drain snake or plumber’s auger to break up and extract debris. Don’t scratch plastic components.
• Mix 1/2 cup baking soda and 1/2 cup vinegar and pour down drains to break up grease and food buildup with fizzing action. Rinse thoroughly.
• Remove drain pumps and filters and soak overnight in a de-liming solution to dissolve mineral deposits that can restrict water flow.
• Avoid harsh chemical drain cleaners as they can damage dishwasher components.

With some perseverance, you can clear out even the most stubborn clogs to get your drains flowing freely again. Just take care to not damage plastic parts.

Preventing Recurring E24 Errors

Once you’ve solved an E24 error, there are some maintenance steps you can take to prevent repeat occurrences:

• Periodically clean the drain filter, drain pump, and hoses. Every few months is ideal, depending on usage.
• Only use dishwasher-safe detergents and don’t overfill dispensers. Suds from hand washing detergent can clog.
• Scrape off or rinse away large food debris before loading dishes. This keeps it from clogging filters.
• Run monthly dishwasher cleaner cycles to flush out grease and limescale.
• Periodically inspect components like hoses, seals, and connections for damage.
• Avoid overloading dishes and ensure water jets can reach all surfaces.
• If hard water is an issue, install a water softener to reduce limescale buildup.

Making drain care and maintenance part of your regular dishwasher routine can go a long way towards preventing annoying E24 errors.

When to Call for Repair Service

While many E24 causes can be resolved with basic troubleshooting, there are instances when professional repair may be needed:

• If the drain pump is defective and needs replacement.
• A problem with the water level sensor or control board not resetting error after drainage issue fixed.
• Severe blockages that cannot be cleared with DIY methods. Professional drain cleaning/rodding may be required.
• Damaged or leaking drain hoses that need replacement.
• An underlying plumbing issue in connected drains or garbage disposal causing backup.
• Repeated E24 errors indicating an underlying problem was not properly identified.
• If any repairs or parts replacements are needed beyond filters and hoses.
• Any time you feel unsure about safely completing a repair. Dishwashers contain electrical components and sharp edges.

Seeking professional service can quickly get your Bosch dishwasher back to full functionality when you’ve exhausted DIY repair options.

As an experienced dishwasher repair tech, I’ve seen my fair share of E24 error codes on Bosch models. This code indicates a drainage issue, usually from a clogged or blocked filter. While frustrating, it’s typically an easy fix.

First, take the filter out and give it a good rinse. A lot of times it’s just some food gunk or calcium buildup slowing drainage. While you’ve got it out, check the drain pump area for obstructions.

Bosch drain hoses also tend to get buildup – grab your trusty zip tie and pull any gunk out. Check the connections are secure too.

If it still won’t drain, the pump itself could be malfunctioning. They’re pretty easy to test and replace if needed. But 9 times out of 10, the E24 is cleared up with a filter cleaning.

Bosch makes a solid dishwasher, so don’t panic if you see an E24. Just a little DIY elbow grease will usually have it draining like normal again. Let me know if you need a hand getting that baby back up and running!
