Q. Dishwasher throws E15 after a spill or a small leak. What’s really happening?
E15 means the leak protection tripped because there’s water in the base. Shut off water, don’t try to bypass the safety, and check for leaks before restarting. If E15 returns, book diagnostics.
Q. E24 won’t go away. Could this be my garbage disposal or air gap?
Yes. E24 = no drain. Beyond a clogged filter/hose, a new disposal with the knockout plug still in or a clogged air gap will trigger it. Reseat the drain pump cover till it clicks.
Q. After a kitchen remodel, my dishwasher started showing E24/E23. Normal?
Happens a lot. Remodels can leave kinked hoses, mis-seated pump covers, or debris in the air gap. Fix those first; if codes return, the drain pump may need testing.
Q. It’s 95°F in the house. My fridge alarms more — heat thing?
High ambient temperature hurts condenser cooling and can push systems toward temp/defrost alerts. Keep toe-kick and coils clean and restore airflow; persistent alarms need diagnostics.
Q. Oven flashed F34 after a long bake/self-clean. Fan issue?
Often, yes. F34 typically points to cooling/airflow (fan or air-switch path). Do one safe reset; if it returns, check cooling fan/switch and venting.
Q. Can hard water really cause dishwasher errors over time?
Hard water builds scale on heaters and flow paths, stressing heating/thermistor control and spray performance. Regular descaling helps; severe scale needs service. See all Thermador dishwasher Error Codes
Q. Power flickered during a storm — now weird alerts. Could it be the power, not the appliance?
Yes. Surges and voltage swings can confuse or damage boards. Use a dedicated circuit and surge protection; if alerts persist post-reset, get diagnostics.
Q. Home Connect keeps acting up. Any quick wins?
Re-pair the appliance, confirm 2.4 GHz and WPA2, and ensure required router ports (443/8080/123) are open. Try a hotspot test to isolate router issues.
Q. Fridge temps drift after big grocery runs or a party. Is that a fault?
Often just blocked vents/door open time. Clear rear vents, check seals, and give it time to stabilize. If alarms repeat with normal use, run diagnostics.
Q. What “first checks” solve the most issues before I call?
Dishwasher: filter, air gap, hose kinks, pump cover click. Oven: single safe reset, listen for fans. Fridge: seals, vents, coil/toe-kick airflow. If codes recur — call.
