Bosch steam oven E5124 error code
Evaporator did not drain during the self-test. E5124 on a Bosch HBE5452UC wall oven with a steam system means the oven ran its self-test and found water still sitting in the evaporator after it should have been pumped out. Bosch service data points at one component: the drain pump, which Bosch calls pump 2, either does not pump at all or is so scaled up that it cannot move the water volume. The parts behind that are the pump unit, its wiring to the steam electronics module, or the module itself.
WHAT THE CODE MEANS
Evaporator did not drain during the self-test
E5124 on a Bosch HBE5452UC wall oven with a steam system means the oven ran its self-test and found water still sitting in the evaporator after it should have been pumped out. Bosch service data points at one component: the drain pump, which Bosch calls pump 2, either does not pump at all or is so scaled up that it cannot move the water volume. The parts behind that are the pump unit, its wiring to the steam electronics module, or the module itself.
SAFE CHECKS — IN ORDER
How to diagnose Bosch E5124 yourself
Walk these checks in order before scheduling service. They isolate the most common causes safely without requiring tools or part replacements.
- 1Power-cycle at the breaker: a built-in wall oven is hardwired, so switch its circuit breaker off, wait 60 seconds, restore power, and start a steam mode again to see whether E5124 comes back.
- 2Run the oven’s descaling program once, all the way through, then re-test. Bosch lists the descaling function as the fix for the case where the drain pump still runs but is too scaled up to empty the evaporator, and hard tap water scales a steam pump faster than the descale reminders assume.
- 3Check the water-hardness setting in the oven menu against your supply. Bosch’s troubleshooting for E5124 includes checking that adjustment and correcting it, because a setting that is too low lets scale build between descaling cycles.
- 4Listen for the drain pump when a steam mode starts or ends, and note whether E5124 appears during the self-test at power-up, at the start of a steam function, or right after descaling. If the display instead says “Tank empty”, that is a different fault (E5121); a tank-level fault logs as E5133.
- 5Do not pull the oven out of the cabinet or open the steam module yourself. Bosch’s next step is measuring mains voltage at pump 2 (140 or 230 volts AC, depending on the model) and then replacing the pump unit or the steam electronics module — a live-voltage test for a technician.

FAQ
Frequently asked questions
What does the E5124 error code mean on a Bosch steam oven?
▾
E5124 on a Bosch HBE5452UC wall oven with a steam system means the oven ran its self-test and found water still sitting in the evaporator after it should have been pumped out. Bosch service data points at one component: the drain pump, which Bosch calls pump 2, either does not pump at all or is so scaled up that it cannot move the water volume. The parts behind that are the pump unit, its wiring to the steam electronics module, or the module itself.
Can I clear the E5124 code myself?
▾
In many cases yes — start with the safe checks listed above before resetting the appliance. Call for service if E5124 comes back after a breaker reset and a complete descaling cycle, if you never hear the drain pump run, or if the steam functions have locked out. A drain pump that does not pump means a pump-unit or steam-electronics-module replacement, and Bosch’s procedure starts with a voltage measurement at the pump, which is a service visit.
How much does it cost to fix a Bosch steam oven showing E5124?
