Bosch WGB246AXUC E23 Error Code | E23 Water Leak Detected

Error e23 on Bosch wgb246axuc: Water leak detected — AquaStop system or leak sensor has detected water in the m. Follow the troubleshooting steps below to diagnose and fix this washer issue. ## What Does E23 Mean on a Bosch WGB246AXUC? Your Bosch washing machine is displaying an E23 error code, which means the AquaStop or leak detection system has found water in the base of the machine. Bosch’s AquaStop technology includes a leakage sensor and a double-walled intake hose. When the sensor detects water in the drip tray under the drum, E23 is triggered and the machine’s water supply is automatically shut off to prevent flooding. The washing machine will not restart until the leak source is identified and the base is dried. ## Fault Details | Field | Value | |-------|-------| | Error Code | E23 | | Appliance | Bosch WGB246AXUC 800 Series 24-inch Front Load Washer | | Fault Type | Water leak detected | | Severity | High | | User Serviceable | No — professional service recommended | | Applicable Models | WGB24600UC, WGB246AXUC, WQB245AXUC | ## Common Causes - Detergent drawer or dispenser housing cracked or leaking — water drips into base

  • Door gasket (door boot seal) torn or cut — water escapes around the door perimeter
  • Drum-to-pump hose connection leaking — loose clamp or cracked hose
  • Water inlet valve body cracked or inlet hose connection loose
  • Drain filter housing or pump body cracked — water leaks at the filter cap area
  • Tub-to-pump or tub-to-outlet hose clamp loose after a service repair ## Step-by-Step Troubleshooting | Step | Action | What To Do | Expected Result | |------|--------|------------|-----------------| | 1 | Turn off the water supply immediately | As soon as E23 appears, turn off the water supply valve behind the machine. This prevents additional water from entering. Do not restart the machine until the leak source is identified and repaired | Water supply secured — no new water entering the machine | | 2 | Tilt the machine to drain the base tray | Unplug the machine. With assistance, carefully tilt the machine forward 45 degrees to drain accumulated water from the base tray. This helps reset the AquaStop float sensor and allows you to see where water is collecting | Water drains from the base; floor or drip pan inspected for leak location | | 3 | Inspect the door gasket for tears | Open the door and examine the full perimeter of the rubber door boot seal. Run a finger along the inner folds — tears or holes often occur at the bottom of the seal where water pools during washing. Even small tears can allow significant water escape | Gasket intact with no tears or holes | | 4 | Check the detergent drawer and dispenser housing | Remove the detergent drawer completely and inspect the housing for cracks. Water can enter through the dispenser and drip into the base if the housing is cracked or if the detergent drawer nozzle seal is damaged | Dispenser housing intact; no cracks or loose nozzles | | 5 | Contact Bosch service to locate and repair the leak | If the door gasket and dispenser are intact but E23 persists, the leak is likely from an internal hose, pump housing, or tub seal. These require professional disassembly to inspect. Contact Bosch at 1-800-944-2904 for repair service | Leak source identified and repaired by technician; E23 resolved | ## Frequently Asked Questions ### Can I use the washing machine with E23? No. E23 indicates an active water leak, and running the machine could allow significant water to escape into your home. The AquaStop system has shut off the water supply as a safety measure. Do not attempt to override this until the leak is fully repaired. ### Why does E23 appear right after installation? E23 after installation often indicates that the machine was not properly leveled (internal water can pool in the sensor area), the door gasket was damaged during transit, or an internal hose was loosened during shipping preparation. Check machine leveling and door gasket condition before calling a technician. ### What is AquaStop and how does it work? AquaStop is Bosch’s anti-flood protection system. It includes a special double-walled water inlet hose with a pressure sensor and a leakage sensor in the machine’s base drip tray. If the inlet hose bursts, the double wall prevents flooding. If internal leaks fill the base tray, the float sensor detects this and E23 is triggered. The water inlet valve closes automatically. ### How much does door gasket replacement cost on a Bosch washer?
