Plunge · in-depth owner report

Machine 1 of 3

Plunge All-In Commercial with auto-doser, cold only · in service from Apr 2024

As of September 29, 2026, Plunge's engineers had found a refrigerant leak in this machine's chiller and proposed replacing it, which would make it the machine's third chiller, along with display, doser-cable and filter-housing parts: a $5,235.39 quote. The quote was still open.

Every problem

What the owner reported, and what Plunge did.

In the order they were first reported.

  1. Controls and appApp or controls only

    The owner reported all three machines offline in the Plunge app that morning, and Plunge's reset steps did not work. The owner removed and re-added each machine in the app.

    Owner account
  2. PowerReported not operating

    The owner came into the studio and found the unit completely off, although the outlet worked; pressing reset and test on the unit's plug made a buzzing sound and nothing happened. Two days later the owner reported a fried and melted wire inside the plug, sent two photos, and wrote that a plunge had been down for two business days. Four days after that, the owner reported that the technician had still not been in touch to arrange the repair.

    Plunge support asked for photos of the GFCI plug, then said a repair was necessary and advised keeping the unit at least five feet from outlets, saying water splashing on an outlet can cause this type of damage. Plunge said the repair was covered under its factory warranty, ordered a free GFCI plug and two fuses, and assigned a technician; when the owner reported no contact, Plunge said it had messaged the technician.

    • Down two business days by the owner's September 24 count.
    • Six days after the first report, the owner still had not heard from the technician (September 22 to 28).

  3. CoolingReported not operating

    The owner reported the unit would not get below 51 degrees despite being set to 44 (it was usually set around 44 to 46), with no triggering event, and passed on a staff report that it had been making a lot of noise nonstop. Replacement parts arrived on September 23 with no contact from the installer. On September 27 the owner wrote in this unit's repair thread that a plunge had been out of commission for two weeks with nothing scheduled and that the business was suffering.

    Plunge support said it could see the compressor struggling on this unit and sent the case to engineering, then said a repair was necessary and the faulty chiller had to be returned. Plunge said the unit should now be covered by the extended protection plan and asked the owner to file a claim, ordered a free replacement 1HP chiller, asked its installation partner to schedule the visit, and reassigned the job to the studio's usual technician after the owner reported no contact.

    • Out of commission for two weeks by the owner's September 27 account, with nothing scheduled.
    • Nine days from the first report to the replacement parts arriving (September 14 to 23), then no contact from the installer.

  4. LeakReported impaired

    During the cooling repair, the owner reported a leak on the auto-doser chemical side, under the lowest blue valve, that had been repaired before but continued to leak chlorine or muriatic acid, and asked for it to be addressed in the same repair.

    Plunge added auto-doser tubing to the repair: the free replacement order of September 18, 2025 lists the tubing alongside the chiller under warranty.

  5. LeakReported impaired

    The owner reported active leaking from the connected Hanna probe and from the valve beneath it, sent videos, and wrote that this exact issue had been repaired about a year earlier. At Plunge's request the owner removed the probe, replaced its thread tape, drained and refilled the unit, and monitored it.

    Plunge engineering reviewed the videos and said it could not tell whether the leak came from the Hanna probe or the ball valve directly beneath it, said slow leaks there are often caused by degrading thread tape, and asked the owner to remove the probe, re-tape it, reinstall it and report back.

  6. Dosing and water chemistryReported impaired

    The owner reported red warning lights on the unit for low ORP and high pH. A week later the owner reported test strips reading 10+ for free chlorine, an oily residue on the water, and a high ORP reading on the Hanna monitor, and asked whether the probe needed recalibrating.

    On June 25 Plunge said engineering saw a leak in the chiller's heat exchanger causing the auto-doser's sensor trouble, recommended a full deep clean for the residue and suggested guests shower before use. Plunge had merged this machine's case with Machine 2's by then, so the reply may concern either machine.

  7. CoolingReported impaired

    Found by Plunge's engineers in the machine's remote diagnostic data, rather than reported by the owner.

    Plunge said its engineering team, based on diagnostic metrics showing extended cooling times, confirmed a refrigerant leak as the root cause and recommended a chiller replacement. On September 29 Plunge sent an invoice pricing the replacement at $3,200 within a $5,235.39 repair proposal for this unit.

    • Six days from Plunge's diagnosis to a priced quote (September 23 to 29). Nothing had been installed by September 29.

Open problemPlunge's answer
Cooling: extended cooling timesPlunge engineering said diagnostic metrics showing extended cooling times confirmed a refrigerant leak as the root cause and recommended a chiller replacement, priced at $3,200 for a Gen 2 chiller fitted to the Gen 1 tub.
App connectivityPlunge recommended a new UI ribbon cable and UI display, saying they address connectivity issues the owner had reported.
Hanna doserPlunge recommended new Hanna power and signal cables, and the invoice adds an AC splitter cable. Plunge also said Hanna reading problems were linked to a known firmware issue, with a fix expected 10 to 14 days after September 23, 2026.
Filter housing and unionPlunge recommended a filter housing assembly and a union repair kit to bring the filter housing to the latest version.
Earlier probe and ball-valve leak (June 2026)Plunge's response in June 2026 was to have the owner re-tape and reinstall the Hanna probe.
Who pays, and what happens if this repair does not holdIn a September 28, 2026 call, Plunge said this round of repairs should fix the problems once and for all. The quote does not say who pays, or what happens if the repair does not hold.

  • Plunge manufacturer warranty

    One year from the original purchase (six months for the auto-doser probe)

    A replacement part keeps the original end date; it does not start a new year. Plunge covered the September 2024 power repair under this warranty. It ended in spring 2025; later repairs went through the extended protection or were paid by the owner.

  • Extended protection, through XCover

    February 28, 2025 to February 28, 2030

    One certificate per machine, each with an $11,990 limit. Plunge sent the September 2025 chiller replacement through this plan.

What the owner did
  • Removed and re-added all three units in the Plunge app to bring them back online after the reset steps failed (May 2024).
  • Inspected the failed plug, found the melted wire and sent two photos to Plunge support (September 2024).
  • Followed up when the assigned technician had not made contact to schedule the 2024 power repair.
  • Answered Plunge engineering's eight-question checklist on clearance, water exposure, dry running, circuit, extension cords, GFCI placement, set temperatures and triggers, and passed on staff observations of nonstop noise (September 2025).
  • Filed the extended-protection claim and sent Plunge the confirmation, as Plunge asked (September 2025).
  • Reported that the replacement parts had arrived with no contact from the installer, and asked to bring in the studio's usual technician (September 2025).
  • Packed the failed chiller for return and asked for the carrier pickup (October 2025).
  • Recorded and sent videos of the probe and valve leak and described the warning lights (June 2026).
  • Following Plunge's instructions, found the probe wrench, drained and refilled the unit, removed the Hanna probe, replaced its thread tape, reinstalled it and monitored for leaks (June 2026).
  • Tested the water with strips and compared the readings with the Hanna monitor (June 2026).
What would show it is fixed
  • A written work order names this physical unit by serial number, the chiller fitted (with its serial), the installation date and the technician.
  • The water reaches and holds the owner's usual set temperature of 44 to 46 degrees through normal commercial use, with cool-down times recorded before and after the repair.
  • No leaks at the Hanna probe, the ball valve, the filter housing, the unions or the auto-doser chemical side after a stated period of operation.
  • The unit reconnects to the Plunge app after a restart and stays connected.
  • Pause and restart work without error codes.
  • The displayed water temperature matches a measured water temperature.
  • Hanna ORP and pH readings agree with test strips, dosing holds the water in range, and the promised firmware fix is installed and confirmed.
  • Each charge is explained: what the labor quantity covers, what the diagnostic fee buys, and who pays under which coverage.
In the owner's words

[September 2024:] I came into the studio today and [the plunge] is completely off. [...] One of the wires in the plug is fried and melted. [September 2025:] It now won't get below 51 degrees, despite being set to 44. [...] I have now had a plunge out of commission for 2 weeks, and my business is suffering because of it. [June 2026:] There is active leaking from the connected probe as well as the valve beneath the probe. This exact issue was repaired approximately one year ago.
