E24 Error: If your Siemens dishwasher has stopped mid-cycle and is disp

If your Siemens dishwasher has stopped mid-cycle and is displaying E24 on the control panel, your appliance is telling you that water isn't draining away properly. This is a high-priority alert that needs addressing, as water sitting inside the machine can lead to unpleasant odours and potential damage if left unchecked. The good news is that E24 faults are often straightforward to diagnose and many homeowners successfully resolve them without calling an engineer. The issue typically stems from one of three components: a blockage in the drain hose, a clogged filter assembly, or a faulty drain pump that's struggling to expel water. Before you reach for your phone to book a repair, it's worth investigating these common culprits yourself. A blocked drain hose might simply contain food debris or a kink that's interrupting flow. The filter assembly, which sits at the bottom of the machine, may be trapping particles that prevent proper drainage. In some cases, the drain pump itself may have failed and require replacement. This guide will walk you through identifying and fixing the problem, potentially saving you a costly service call.

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.

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.

This genuine OEM drain hose, reference 00266916, is designed specifically for Bosch and Siemens dishwashers and offers reliable performance you can trust.

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.
