E13

Water Container Full

Severity

Low

Your Bosch Dryer stopped working and is showing error E13, which corresponds to a fault called "Water Container Full". This is one of the most searched error codes for this appliance — you are not alone, and there is a clear fix.

Owner's Summary

This isn't really an error — your condenser dryer's water collection container is full and needs to be emptied. Condenser dryers pull moisture out of the air and store it as liquid water that needs periodic dumping, usually every 2–3 loads.

Symptoms

Bosch condenser dryer stops mid-cycle, E13 displayed, water tank indicator lit

Common Causes

Condensate water container full and needs emptying
Water level float switch stuck
Blocked drain hose if connected to direct drain
Float switch malfunction

How to Fix

1 Remove and empty the condensate water container
2 Reinstall container firmly until it clicks into place
3 Check float switch inside the container for debris
4 If using a direct drain hose, inspect for kinks or blockages

Tools You'll Need

Pliers Towels / Bucket Flashlight

These are simple, low-risk fixes most homeowners can do with tools already in a basic toolbox.

Technical Explanation

A float switch inside the condensate container rises with water level and triggers an electrical signal to the control board once full. E13 is the board's response to this signal, halting the cycle to prevent overflow inside the cabinet.

Is It Safe to Keep Using?

No risk. This is routine maintenance, not a malfunction.

Technician's Pro Tip

If E13 appears immediately even after emptying the container, the float switch itself may be stuck in the 'full' position from mineral buildup. Rinse the float mechanism with water to free it before assuming it needs replacement.
