Instant Pot Duo Plus 9-in-1 8 Qt: problems, parts and running costs

Checked: 2026-10-20

Summary

The 8-quart Duo Plus (SKU 113-0058-01) mostly needs program tuning rather than repairs: the rice, sous vide and cake presets need changed settings, steaming and slow cooking run long, and the inner pot has no handles. [1][2][3] Running costs are electricity alone — a 1200 W heater, sealing rings as the only consumable with two spares in the box, and no app or subscription. [1][2] It is a good buy at or below the band where the 6-quart sibling sits, since the extra capacity comes with the same nine functions; the often-quoted 75 dB steam release and 15 PSI figures were measured on the 6-quart sibling, not on this 8-quart. [2][3][8]

Common problems and fixes

Rice program overcooks at its default setting — the default 12-minute program gave sloppy, mushy rice in the only hands-on test of this platform, run on the 6-quart sibling; it came out better at a 1:1.25 rice-to-water ratio, with 8 to 10 minutes suggested instead of 12. [2] Shorten the time and change the water ratio before you suspect the machine, and scale the ratio for the bigger 8-quart pot. Nothing is broken, so the warranty is not involved.
Sous vide cannot hold a temperature — the mode has no water-temperature setting and no live temperature display, so a 90-minute creme brulee came out runny and unset. [2] There is no hidden setting to find; for dependable sous vide you need a separate circulator. It is the least controllable program on the machine, and not a fault you can claim.
Cake program gives a lopsided cake — a store-bought mix baked on the default 30-minute cake setting came out moist but deflated and lopsided, and only a 6-inch pan fits the inner pot. [2] Expect to trim the top and to buy a 6-inch pan for this program. A lopsided cake is a result, not a defect, so the warranty does not cover it.
Steam and slow cook run long — butternut squash only softened after raising the pressure level and extending the total steam time to 20 minutes, against 10 minutes on the entry Rio, and the default beans setting took 6.5 hours where pressure cooking took 40 minutes. [2] Plan the longer times and use the pressure program for beans and other long cuts. The maker’s cooking-time table also lists 2 cups as the minimum liquid for the 8-quart pot, so scale liquid up with batch size. [1]
The pot has no handles and the machine is bulky — the Duo Plus inner pot carries no handles, so a full 8-quart pot has to be lifted rather than carried, and the published size of the 8-quart is 14.53 by 14.53 by 13.98 with no unit stated on the page; the 6-quart sibling weighs 12.3 lb and was hard to store away between uses. [1][2] The steam rack in the box has handles; the pot does not. Measure the counter and the cabinet first, and expect no help from the warranty here.
Clicking while preheating and cooking — one owner of the 6-quart Duo Plus reported clicking sounds during preheat and cooking and said the pot kept cooking normally. [4] It is a single report with no confirmed fault behind it, so treat the sound as something to check rather than a known failure; if a cook does not finish normally, contact support on 1-800-828-7280. [1]
Three different 8-quart machines sit on shelves — the current 113-0058-01 has the WhisperQuiet lid, 9 cooking functions and 25 recipe presets; the earlier 113-0054-01 has no WhisperQuiet lid and its listings advertise a sterilize program the current model does not have; and the Duo 8QT is a separate machine with 7 functions and 13 customizable programs. [1][5][6][9] Read the model number on the base before you buy and again when the box arrives; a mismatch is a return decision, not a repair. [1]
One-year warranty that does not pay shipping — the 1-year limited warranty covers authorized-retailer purchases by the original owner, is not transferable, and lets Instant Pot repair or replace at its own discretion; the company states it is not responsible for shipping costs for warranty service. [1] Exclusions include normal wear and tear, commercial use, use of unauthorized parts and repair by anyone the company did not direct, and a replacement unit carries 12 months of cover. [1]

Parts and consumables

Sealing rings and gaskets — the consumables the maker names for this model; two spare sealing rings ship in the box, so nothing has to be bought on day one. [1][2] No part number, no published cost and no replacement interval are available for SKU 113-0058-01, and there is no owner data on how often they are changed. [1]
Inner pot (18/8 stainless steel with a tri-ply bottom) — the pot itself, and the part that gets replaced if it is damaged; the 6-quart spec sheet for this platform lists “dishwasher safe: inner pot only”, so the lid and base are hand-wash. [2] No published cost, part number or replacement interval is available, and spare inner pot availability for this SKU is unknown. [1]
Steam rack with handles — included in the box, and the one accessory with handles; no replacement cost is published. [1][2]
Control board and lid hardware — the maker’s page lists no parts catalog and no service pricing for the Duo Plus line, so availability and cost for the control board, gaskets and lid parts for SKU 113-0058-01 are unknown. [1]

Yearly running cost

Electricity is the only recurring cost. The heater is rated at 1200 W, so one hour of continuous heating is 1200 watt-hours; pressure cooking draws less because the element cycles, and no cooking-hour figure has been published for this model. [1][2] Multiply your cooking hours by 1200 watt-hours, convert to kilowatt-hours and apply your own rate — no electricity rate is given anywhere, so no dollar total can be published. The maker’s claim of 60% less energy than a conventional oven carries no published method. [1]

On the parts side there is nothing to buy on a schedule: sealing rings and gaskets are the consumables, two spare sealing rings come in the box, and no costs or replacement intervals have been published for them. [1][2] There is no app or subscription requirement for the 25 on-device presets; a buyer who wants them in an app would need the Wi-Fi Pro Plus line instead. [1][3]

When it is a good buy

The maker’s page publishes no price for the 8-quart and the retailer listings that carry one could not be read, so no street price for this model could be confirmed. [1][10] Read it against the closest dated anchors: the 6-quart sibling’s price box listed Macy’s $139.99, Lowe’s $142.21 and Best Buy $169.12 in September 2024, with the entry Rio at $99, and the UK list level of the 6-quart at £129 with £82 the lowest seen. [2] The 8-quart line has one older anchor: a 2019-2020 giveaway page put a stated retail value of $159.95 on the previous generation. [7]

At or below $139.99 — the 6-quart sibling’s Macy’s level in September 2024. At that level the 8-quart is the better buy for a family or for batch cooking: the same 9 functions, the same WhisperQuiet release and the same 1-year warranty in a pot that serves up to 8. [1][2]
$139.99 to $169.12 — the Lowe’s and Best Buy band for the 6-quart in September 2024. Defensible for batch cooking, large cuts of meat and gatherings, but the smaller model is the better buy if your cooking rarely fills a bigger pot. [1][2]
Above $169.12 — capacity stops being the deciding factor, and the app-controlled Pro Plus tier is the better use of the money. [3]

Alternatives:

Instant Pot Rio — the better choice when the rice, cake and sous vide programs will go unused; the roundup that calls the Duo Plus its most versatile model lists the Rio first, and its price box put the Rio at $99 in September 2024. [2][3]
Instant Pot Rio Mini — the better choice when budget and counter space matter more than the extra programs; it is the roundup’s budget pick. [3]
Instant Pot Pro Plus Smart — the better choice when you want the guided presets in an app instead of on the panel; it is app-controlled, and what it costs was not read here. [3]
