Real diagnostic steps and real repair examples from the techs who service cold plunges nationwide — not generic advice written by someone who's never opened a filter housing.
Running but the water's not getting cold, or it's lost temperature it used to hold. Bad compressors, icing, and low-flow causes.
Diagnose it →No flow, low flow, or a display reading that doesn't match reality. Filters, pumps, impellers, and power supplies.
Diagnose it →Water where it shouldn't be — filter housing, base, or a fitting. How to find the real source before assuming the worst.
Diagnose it →Dead display, burnt connections, melted power strips, or a chiller that's genuinely done. What's actually the chiller vs. what isn't.
Diagnose it →Every example on these pages comes from an actual Cold Standard service visit — the symptom the customer reported, what our tech actually found on site, and what fixed it. We anonymize the customer; we don't fabricate the diagnosis.
Not every "won't cool" or "won't stop leaking" problem has the same cause, and a lot of what gets fixed unnecessarily (or missed entirely) comes down to skipping steps. These pages walk through the same sequence our techs run in the field — cheapest and most likely causes first — so you know what you're actually dealing with before you call anyone.
Every diagnostic visit includes a full inspection, not just the symptom you called about — and a same-day report with photos.
