E24 Error: If your Bosch dishwasher has ground to a halt and is display

If your Bosch dishwasher has ground to a halt and is displaying the error code E24 on its display panel, you're likely dealing with a drainage problem. This error indicates that water isn't draining away properly from your machine, which is why it's stopped mid-cycle to prevent overflow and potential water damage to your kitchen. The good news is that E24 faults are often fixable without calling out an engineer, saving you considerable time and expense. In most cases, the issue stems from a blockage somewhere in your dishwasher's drainage system rather than a complete mechanical failure. The most common culprits are a clogged drain filter, a blocked or kinked drain hose, or occasionally a faulty drain pump. The filter assembly is typically the easiest to check and clean yourself, often requiring just minutes of your time. The drain hose, which carries water out of your machine, can sometimes become twisted or contain debris that restricts water flow. Less frequently, the drain pump itself may have failed, though this is less likely. Before you worry about expensive repairs, this guide will walk you through identifying and resolving the problem.

Drain Pump

OEM: 00651628

# Drain Pump for Bosch and Siemens Dishwashers If your dishwasher is leaving standing water at the bottom or won't drain properly, a faulty drain pump is likely the culprit. Over time, this essential component can wear out or fail completely, preventing water from being expelled during the wash cycle. This genuine OEM drain pump (reference 00651628) is designed for Bosch and Siemens dishwashers and will restore your appliance's drainage function. Installation is straightforward, rated at difficulty level 2, making it an achievable DIY project for most homeowners. When fitting the new pump, remember to unplug your dishwasher and turn off the water supply first. Take a photo of the old pump's wiring connections before removal, so you can easily reconnect the replacement. Most models require you to remove the lower spray arm and filter basket to access the pump beneath the tub. Before ordering, verify your dishwasher's E-Nr model number from the appliance data plate, usually found on the side wall of the cabinet. This ensures complete compatibility with your specific machine.

Filter Assembly Complete

OEM: 00427903

Most people complete the installation in under five minutes. Before ordering, please verify your dishwasher's E-Nr model number, which you'll find on the rating plate inside the door frame. This ensures you're purchasing the correct part for your specific machine and helps avoid any compatibility issues.

Drain Hose

OEM: 00266916

# Drain Hose for Bosch and Siemens Dishwashers Water pooling at the bottom of your dishwasher or slow drainage during the wash cycle usually points to a blocked or damaged drain hose. Over time, this essential component can deteriorate, crack, or become kinked, preventing water from flowing away properly. Replacing it is often the quickest way to restore your appliance to full working order. This genuine OEM drain hose, reference 00266916, is designed specifically for Bosch and Siemens dishwashers and offers reliable performance you can trust. Installation is straightforward and requires minimal DIY experience, typically taking just fifteen to twenty minutes with basic tools. When fitting the new hose, make sure it isn't bent at sharp angles once connected, as this can restrict water flow and cause the same problem to recur. Route it gently away from the dishwasher to your waste outlet. Before ordering, please verify your appliance's E-Nr model number, which you'll find on the information label inside your dishwasher door. This ensures complete compatibility and a perfect fit for your specific model.
