Pump Housing & Sump

About This Part

# Pump Housing & Sump When your Bosch or Siemens dishwasher fails to drain properly or makes unusual grinding noises, a worn pump housing and sump is often the culprit. Over time, this critical component deteriorates through normal use, leading to water pooling at the bottom of your machine or a complete loss of pumping ability. This genuine replacement part (OEM reference 00263056) restores your dishwasher's drainage system to full working order. It's the heart of your appliance's water circulation, so replacing it when worn prevents further damage to connected components. Installation difficulty is rated at level 3, making this a moderately challenging job for a confident DIYer. Before you start, locate the pump housing beneath the spray arm assembly and take photographs of the hose connections as you remove them. This simple step makes reconnection straightforward and prevents costly mistakes. The task typically requires basic tools and takes around 90 minutes to complete. However, it's absolutely essential that you verify your dishwasher's E-Nr model number matches our compatibility information before ordering. This ensures you receive the correct part for your specific machine.
