Presto 01784: problems, parts and running costs

Checked: 2026-10-21

Summary

The complaints that come up most are a dial gauge that drifts, sticks or leaks steam at its joint, a canner that is slow and thirsty to bring up to pressure, and a thin aluminum body that dents, stains and can warp if it boils dry [16][17][18]. Keeping it running costs about $8.33 a year for the sealing ring and overpressure plug kit that Presto asks you to replace every three years, plus single-use jar lids, and nobody has measured the energy it takes because the heat comes from your cooktop [5][2]. On induction or a glass top it is worth the $215.99 that Presto, Home Depot, Target and Everything Kitchens asked in October 2026, since almost no other full-size stovetop canner will heat on those surfaces, while on gas or an electric coil burner the $185.99 aluminum 01781 does the same job [1][24][18][26][14].

Common problems and fixes

Dial gauge drifts, sticks low or reads high — Presto’s manual asks for an accuracy test before every canning season, and NCHFP guidance is to replace a dial that is more than 2 psi off at the reference pressures. Owners report a gauge stuck at 5 psi with the lid off and steam escaping near the gauge base, another that would not get past 10-11 psi, and a May 2025 post describing a gauge reading 2-3 psi high after only 5-6 loads. Fix: have the dial checked at a county extension office, which often tests for free, and fit part 85772 when it is out of tolerance. The dial is a wear part, so the 12-year limited warranty does not cover it. [2][7][16][19][20][21]
Steam escapes at the gauge joint — the gauge only seals when it sits correctly on its black flanged compression gasket, washer and nut, and a poorly seated gauge is what lets steam out at the connection; a retailer-syndicated owner account describes exactly that, along with a check at an extension office. Fix: reseat the gauge and replace the fastener pack 82248 if the hardware is worn, and never work on a pressurized joint. Not a warranty item. [2][13][22]
Hardened sealing ring and steam around the lid — the manual describes a hard or deformed gasket as the cause of steam around the lid, and says to replace the sealing ring and the backup plug together at least every three years, or sooner if the ring is hardened, pitted, damaged or leaking. Fix: fit the 09985 kit; wear parts are excluded from the 12-year limited warranty. [2][5][16]
The double-deck jar counts need a rack that is not in the box — the 20-pint and 26-half-pint pressure-canning maxima need a second rack, and only one 85707 comes in the carton. Fix: add a second rack, listed at $15.50 (Presto, October 2026). [2][9][17]

Parts and consumables

Sealing ring and overpressure plug kit 09985 — $25.00 (Presto, October 2026), confirmed in Presto’s catalog as compatible with the 0178410 model family. The manual says to replace the ring and the plug together at least every three years, or sooner if the ring is hardened, pitted, damaged or leaking, which works out to about $8.33 a year across a three-year cycle; wear parts are not covered by the warranty. [5][4][2]
Overpressure plug 09915 — $5.00 (Presto, October 2026) if you need one on its own; it sits inside the 09985 kit, so normally it is replaced as part of that set, and a plug that has been expelled under pressure should not be reused. [6][2]
Dial gauge 85772 — $26.50 (Presto, October 2026), supplied with the compression gasket, washer and nut the gauge joint needs. Replace it when the calibration cannot be verified or the dial is more than 2 psi off at the reference pressures, not on a calendar. [7][16]
15-psi pressure regulator 09978 — $14.00 (Presto, October 2026); it is the only regulator Presto lists for this model and it is not a routine consumable. Never add mass to it: in February 2025 a reviewer reported gluing coins to the 15-lb weight and Presto support replied that the modification is not recommended because the supplied regulator already rocks at 15 psi. [8][4][18]
Canning/cooking rack 85707 — $15.50 (Presto, October 2026); one is included, and owners buy a second to reach the advertised 20-pint and 26-half-pint loads. [9][17]
Air vent cover-lock gasket 85659 — $4.99 (Presto, October 2026); replace it when it is hard, cracked or torn. [10][2]
Air vent cover lock 85407 — $10.00 (Presto, October 2026); a genuine replacement only if the lock is defective. [11][4]
Vent pipe and nut assembly 85608 — $10.00 (Presto, October 2026); clean the vent pipe before every cycle and replace worn parts on Presto’s guidance. [12][2]
Gauge fastener pack 82248 — $4.99 (Presto, October 2026): the white compression gasket, metal washer and nut for the gauge joint, the fix when steam escapes there. [13][2][22]
Three-piece 5/10/15-lb weight set — the common owner add-on for lower-pressure processing, but Presto’s exact-model catalog for the 0178410 lists only the 15-psi 09978, so get written confirmation before fitting one. [4][17]

Yearly running cost

The recurring spend is the sealing ring and overpressure plug kit: $25.00 (Presto, October 2026) every three years as the manual requires, which works out to about $8.33 a year, and the $5.00 plug is normally replaced as part of that kit rather than bought again. The dial gauge gets an accuracy test every season, often free at a county extension office, and a new 85772 at $26.50 (Presto, October 2026) is needed only when the calibration cannot be verified, not on a fixed schedule. Flat jar lids are single-use, so 7 new lids per 7-quart batch, on top of the jars and bands you already own. Heating energy is the unknown: the canner has no element of its own, the consumption belongs to your cooktop, and nobody has measured it for this model. There are no subscriptions and no service fees.

When it is a good buy

In October 2026 the 01784 was listed at $215.99 by Presto, Home Depot, Target and Everything Kitchens, and Walmart’s page showed $159.69 for the induction-capable 23-quart model but the listing was out of stock when checked, so treat that figure as a number rather than an offer [25][26]. On the bands: an authorized new canner at $160-185 is a strong value in an induction kitchen, $186-216 is fair when you genuinely need induction, above $220 it is worth checking other authorized stock or waiting for a promotion, and above $250 you are paying a third-party markup. The Presto 01781 23-quart aluminum canner at $185.99 direct from Presto (October 2026) is the better choice on gas or an electric coil burner, where the magnetic base buys you nothing, and it carries the same 12-year warranty. The Presto 01755 16-quart at $165.99 at Target (October 2026) is the better choice when the 23-quart overwhelms your burner or space is tight; Presto’s comparison chart puts it at 10 regular pints against 20 on the 01784, and it cannot run on induction [15]. The All American 921 21.5-quart, a gasket-free canner listed at $449.95 by an authorized seller with a backorder into late November, is the better choice if you want a metal-to-metal seal and are not on induction, since it is not confirmed induction-compatible [27]. If the objection is watching a dial and learning the venting routine, the plug-in Presto Precise electric canners take that work on, at a higher cost.
