What Does E4 Error Mean on Hoover XS-4A4M4PB?

Error E4 on Hoover XS-4A4M4PB: Water leak, Make sure the drain pipe isn’t bent, trapped or. Follow the troubleshooting steps below to diagnose and fix this dishwasher issue. E4 indicates a water leak detected in your Hoover XS-4A4M4PB washing machine. This is a medium-severity error that most users can resolve themselves by checking the drain system and cleaning accessible parts. Immediately disconnect power, inspect the drain hose and filter for blockages, and remove standing water to prevent damage. If leaks persist after basic checks, professional service may be required. ## What Does E4 Mean? The E4 error code specifically signals that the Hoover XS-4A4M4PB’s internal sensors have detected water where it shouldn’t be, triggering leak protection. According to Hoover’s technical documentation, this occurs when water accumulates in the base pan for more than 90 seconds during operation. The machine will automatically pause its cycle when E4 appears to minimize water damage risk. This differs from other water-related codes like E2 (water supply issue) or E3 (draining problem), as E4 specifically relates to containment failure. ## Possible Causes 1. Kinked or crushed drain hose - The 1.5m flexible drain hose behind the machine has sharp bends exceeding 45 degrees 2. Clogged drain filter - Debris accumulation exceeds 30g in the circular filter behind the bottom access panel 3. Obstructed siphon - The U-shaped siphon tube under the drum contains hardened detergent residues 4. Loose water inlet connections - The hot/cold water supply valves aren’t hand-tightened to 8-10Nm torque 5. Damaged door seal - The 4mm-thick rubber gasket shows tears longer than 5mm ## Troubleshooting Steps | Step | Action | Expected Result | |------|--------|-----------------| | 1 | Unplug machine and wipe standing water | Dry floor around appliance | | 2 | Inspect drain hose path (max 45° bends) | Straight hose without compression | | 3 | Clean filter (rotate counterclockwise) | No debris falls out | | 4 | Check siphon tube under drum | Water flows freely when poured | | 5 | Verify door seal integrity | No visible gaps or damage | | 6 | Reassemble and run diagnostic cycle | Error doesn’t reappear | Allow 30 minutes between tests for sensors to reset completely. ## When to Call a Technician Contact Hoover-certified repair if:
