Problems, parts and running costs

Summary

A 1560-watt countertop blender with six preset cycles and a WildSide+ jar, built for people who blend frozen fruit, fibrous greens and nut butters most days. Check where you buy it: the 2-year warranty only covers units from Blendtec or an authorized dealer, and the jar’s gasket and bearing assembly cannot be replaced on its own.

Strengths

  • Three separate test programs measured it, and all three liked its results with frozen and fibrous ingredients.
  • Chickpeas and olive oil became hummus in under a minute, which Tom’s Guide calls unusual for a machine in this class.
  • The six presets and countdown timer cover work that would otherwise need other appliances, and the icon panel needs the manual about once.
  • At 7.3 lbs it was the lightest of the large blenders Tom’s Guide tested, so it moves without a struggle.
  • The blades are blunt, which keeps the jar easy to wash and leaves nothing sharp spinning down there.

Weaknesses

  • Loud. Tom’s Guide measured 108.2 dB and called it one of the loudest blenders it tested; RTINGS lists “Very loud” as a con.
  • Ice results are contested: TechGearLab got snow in seconds, Tom’s Guide found shards and chunks left in the jar’s bottom corners.
  • The jar’s gasket and blade assembly is not user-replaceable, and a replacement WildSide+ jar lists at $139.95.
  • The LCD hazed white through Tom’s Guide’s testing and did not look like a washable film.
  • Cleaning by hand is awkward in the jar’s corners; TechGearLab scored ease of cleaning lowest of its five categories.
  • Buying from an unauthorized seller voids the warranty, and some storefronts advertise this blender far below list.

Smoothies, hummus and ice

RTINGS scored it 8.5 out of 10, measured it at 15.2 × 7.1 × 7.9 in and 7.3 lbs, and lists a very smooth blend with fibrous ingredients among its strengths. TechGearLab put it at 89 out of 100, third of fifteen blenders tested, and called it simple, reliable and long-lasting. Tom’s Guide named it Editor’s Choice. That is more independent testing than most blenders in this class get.

The performance claims hold up. Tom’s Guide’s reasons to buy were large capacity, great hummus and strong smoothies, and the 1560-watt motor whipped chickpeas with olive oil into creamy hummus in under a minute. TechGearLab’s green shake came out evenly consistent with no ingredient separation and no built-up foam, and needed no tamping. Taste of Home, running a 75-hour test program, got a well-blended smoothie with a few rice-size date chunks left in the colander, very finely crushed ice from a half-jar of load, and peanut butter from four cups of peanuts.

Ice is where the outlets disagree, so treat the marketing line carefully. Blendtec’s product page says the motor turns ice to snow in mere seconds. TechGearLab said that held up in their testing. Tom’s Guide found it prone to leaving frozen shards and ice chunks in the pitcher’s bottom corners and listed inconsistent ice crushing as a reason to avoid. TechGearLab tested small batches of frozen margaritas, which is the most likely reason for the split, but neither outlet states its test load, so nobody can settle it from the published reviews.

Noise

Every outlet that measured it flags loudness. Tom’s Guide recorded 108.2 dB and called it one of the loudest blenders in its group. RTINGS lists “Very loud” as a con without publishing a figure in the readable summary. TechGearLab averaged 84 dB on the Smoothie setting and judged it no louder than other comparably powerful blenders.

A gap that wide is a measurement difference, not a number to average: neither outlet states its distance, load or averaging method. The direction of the complaint is not in doubt. In a small apartment, plan on it before anything else.

The jar is the part that wears out

Blendtec says plainly that jars are a wear item that will need replacing over time, and the owner reports follow a consistent sequence: more noise than before, then black shreds on the base when the jar is lifted off, then liquid leaking out of the bottom. iFixit gives the mechanism for this product family — the blade and bearing assembly attaches to the plastic jar with a large rubber gasket, and if the bearing seizes the race spins and shreds the gasket, with smoke sometimes following. A Blendtec employee statement quoted on Reddit dates the problem to roughly the 3-5 year mark on jars made before 2018, when Blendtec changed the gasket material.

Because that assembly is not user-replaceable, the repair is the whole jar. A replacement WildSide+ jar lists at $139.95 (Blendtec, 2026-10) and carries its own 3-year warranty. The larger WildSide Flow jar is $99.95 (Blendtec, 2026-10) with 40 oz of blend capacity.

Upkeep is short. Blendtec’s manual documents cavitation — when ingredients are too cold or too solid the blade can spin in an air pocket — and asks you to keep frozen ingredients no colder than 10 °F (-12 °C), then power-cycle by unplugging, waiting 5 seconds and replugging. Named error codes include OVERTEMP, Reset Error, NO TEMP. SENSOR and No Zero Crossing. A first-party review also warns that water left in the jar will leak out of it and, if the jar sits on the base with water inside, down through the base. Rinse the jar right after use and invert it to dry.

Warranty and where to buy it

Two years parts and two years labor. That figure is on Blendtec’s warranty schedule for the Total Blender and repeated by Tom’s Guide. Any 8-year warranty number attached to this blender online belongs to the Designer 625 and 650 or to the older TB-621-20. Coverage applies only to units bought from Blendtec or a Blendtec authorized dealer in the US or Canada, and Blendtec reserves the right to reject claims on products from unauthorized sellers. Registering the product is not required.

One number decides whether any of this applies to you. Blendtec treats a blender running more than 3,000 cycles a year as commercial use, and commercial use voids the warranty. If your plan is a small juice bar, a gym or a church basement, this is the wrong machine.

One dated motor failure is worth naming. An owner who bought a Total Blender Classic with WildSide+ jar in late September 2025 got “Overloaded” errors after about 10 days and fewer than 30 blend cycles, across more than 20 ingredient orders. The RMA took almost 3 months — the unit came back in March 2026 — and the fault returned within three uses. One report is not a failure rate, but nobody has published a failure rate for this motor either.

Is it worth it?

Three test programs liked this machine, which is a stronger record than most blenders in this price band can offer. What you are buying is a 1560-watt motor that handles frozen and fibrous ingredients well, plus a jar that will probably need replacing once.

Where you buy matters more than most of the spec sheet. Blendtec’s store listed the black WildSide+ model at $399.95, and its collection page showed the same blender at $349.95 on sale (Blendtec, 2026-10). Home Depot carried model TB-621-25 at $389.99. Storefronts advertising this blender 60-70% below list are not established Blendtec channels, and coverage does not apply to units from them.

On price: at or below $300 it is well worth it on what three outlets measured, under every authorized US price visible then. In the $300-350 band it is fair, and the $139.95 jar becomes the dominant lifetime cost. Above $400 it is hard to justify, and the cheaper Classic 575 in the same line gets the same 2-year warranty. Check the store panel above for current prices.

Which model this is

This page covers the Total Blender Classic with the WildSide+ jar in black, model TB-621-25, barcode 851992000055. The pomegranate body is a separate model, TB-631-25, on the same motor. The same base also ships with a FourSide jar as its own listing, and the Consumer Reports test data often quoted for “Blendtec Total Blender” came from that older TB-621-20 configuration, not this one.

Watch the capacity in retailer titles. Some listings call this jar 90 oz, but that figure matches Blendtec’s larger WildSide Flow jar. Blendtec publishes 36 oz max liquid fill for the WildSide+ and states no total brim figure, and RTINGS measured the blending capacity at 36 oz. The Amazon listing for the black model is ASIN B00JBIP6EC.
