Bosch Washer Error Code 23

Error code 23 means the Aqua Stop leak protection system has been triggered by water collecting in the base pan of the washer. The float switch in the bottom tray has risen and signaled the control board to shut the machine down. This could indicate a real leak in the water system, a stuck float, or a fault in the switch wiring. The washer will not resume operation until the underlying issue is resolved and the base pan is cleared of water.

No, you should not attempt to run the washer while error 23 is active. The machine has shut down specifically to prevent water damage to the electrical components in the base of the unit. Running it in this condition risks electrical hazards and further damage. Address the leak or switch fault before resuming use.

Repair costs vary depending on the root cause. Replacing a door boot seal typically runs in the range of $100 to $200 including parts and labor, while a new inlet valve or pump seal repair may cost between $150 and $300. If the Aqua Stop float switch itself is the only faulty component, the fix is generally on the lower end of that range. Wiring harness issues may fall anywhere depending on the extent of the damage.

Start by tilting the machine slightly forward to allow any water in the base pan to drain out, then inspect all internal hoses, the door boot seal, the pump, and the inlet valve for signs of leaking. Check the Aqua Stop float switch for mechanical freedom and verify continuity in its wiring harness. Once the leak source is repaired or the faulty switch is replaced, the error should clear on restart.

A basic power reset will not permanently clear error 23 if the underlying fault is still present. The Aqua Stop float switch will continue to signal a fault as long as water remains in the base pan or the switch is defective. You must remove the water from the base tray and repair the root cause before the error will stay cleared after a reset.
