Samsung EHS 507 fault code

What it means

Compressor stopped by high-pressure switch

The high-pressure switch has operated. On a water-condensing machine, poor water flow is the first suspect — not the refrigerant circuit.

UK models this code applies to

From the Samsung service literature we hold (Samsung MWR-WW10N user & service manual DB68-08470A-17 (Appendix: error codes)) — not a scraped list.

Now the harder half: proving what caused it

507 names a symptom, not a root cause. In the app, the same code opens a guided investigation: what to measure first, the expected values for your exact model, and an honest verdict — including “nothing in this machine is broken” when that's what the readings say.
