# Dishwasher Buying Mistakes to Avoid > Common dishwasher buying mistakes that lead to the wrong model: place-setting capacity, installation, noise level, and detergent choice, based on specs and buyer reviews. Canonical: https://mizaanhome.com/en-sa/blog/dishwasher-buying-mistakes-to-avoid/ Last updated: 2026-08-17 --- The biggest dishwasher buying mistakes are choosing a place-setting count without measuring actual household size, overlooking installation and plumbing requirements before ordering, skipping the noise level check, assuming any detergent tablet works with Saudi Arabia's hard water, and relying on price alone instead of checking the consensus of buyer reviews. Each of these usually ends in buyer's regret or a unit that gets used less than expected. Here's each mistake broken down, and how to avoid it. ## The quick answer **The biggest dishwasher buying mistakes are not matching place-setting count to your household size, ignoring that full-size units need a real water and drain connection, buying a model without checking its noise level, using a random detergent tablet with hard water, and judging on price alone without checking buyer reviews.** The fix for each is simple: count how many people you actually wash for, confirm you can commit to installation before ordering, check the decibel rating if one is listed, choose a tablet formulated for hard water, and weigh price against the consensus of reviews together. ## Key points - **A dishwasher works by spraying hot water mixed with detergent over the dishes, then rinsing and drying them**, so spray and drainage efficiency affect the wash result as much as the program you pick ([dishwasher definition from Britannica](https://www.britannica.com/technology/home-appliance)). - **Place-setting count should be measured against how many people you actually wash for**, not price or the unit's outward shape. - **Full-size units need a proper water and drain connection**, while countertop units get by with a much simpler setup straight on the faucet. - **Noise level is a factor buyers often forget**, especially in kitchens open to the living area, common in Saudi homes. - **The cheapest price isn't always the best value**, the consensus of buyer reviews is a more reliable signal of real-world performance. ## Mistake one: ignoring place-setting count versus actual household size Many buyers choose a dishwasher based on price or available kitchen space alone, instead of counting how many people they actually wash dishes for in one meal. A capacity smaller than needed means running the machine twice a day to clear the household's dishes, while capacity much larger than needed costs more and takes up more space with no real added benefit. The practical rule: 12 place settings, common on full-size units, comfortably covers a family of four or more in one load, while a smaller countertop unit suits one to three people only. For the full breakdown of what each number actually holds, see [dishwasher place settings explained](/en-sa/blog/dishwasher-place-settings-explained/). ## Mistake two: overlooking installation and plumbing requirements before buying A full-size unit needs a proper water line and drain connection, which is real plumbing work that may need a technician, not just placing the unit and switching it on. Many buyers order the unit first and only then discover their kitchen isn't set up for that connection, ending up with an unexpected installation cost or a machine that sits unused for weeks. If you're renting or would rather not touch your kitchen's plumbing at all, a countertop unit skips that commitment entirely and only needs a simple adapter that fits directly onto the faucet. Settle this decision before you look at any specific model, since it determines which category you're actually choosing from. ## Mistake three: skipping the noise level check before buying Kitchens open to the living area are common in Saudi homes, so running a loud dishwasher while hosting guests or watching TV is something many households notice and dislike. Before buying, check the decibel rating listed in the specs if one is given, since a lower number means a quieter cycle. If no rating is listed in the listing, the practical fix regardless of the number is to run the dishwasher overnight once the household is asleep, or while everyone's out, which removes the problem entirely no matter how loud the unit actually is. ## Mistake four: assuming any detergent tablet works with Saudi Arabia's hard water Water in many parts of Saudi Arabia is relatively hard, which means a regular detergent tablet can leave spots or a dull white film on dishes and glassware even after a cycle finishes successfully. The cause is mineral buildup in the water, not a fault in the machine, and the fix is usually a detergent tablet formulated to handle hard water, or adding rinse aid to the cycle. Skipping this detail before buying leads some buyers to assume their dishwasher is broken when the actual issue is the detergent they're using. ## Mistake five: relying on price alone instead of checking the consensus of reviews The cheapest price is tempting, but it isn't always the best value. A much cheaper model may mean a smaller capacity, fewer programs, or a less consistent wash result according to buyer reviews. We'll be upfront here too: the dishwasher assortment on Amazon.sa is relatively limited right now, so it's better to weigh price against the capacity you actually need and the consensus of reviews together, rather than picking the lowest number on the page. To compare actual price tiers, see [dishwasher prices in Saudi Arabia](/en-sa/prices/dishwasher-prices/). ## Quick table: mistake versus fix | Mistake | Why it hurts | The right fix | |---|---|---| | Place-setting count that doesn't match household | Repeated cycles or wasted space | Match place settings to actual household size | | Overlooking installation requirements | Unexpected plumbing cost or an idle unit | Confirm the water and drain connection before ordering | | Skipping the noise level check | Disruption in a kitchen open to the living area | Check the decibel rating, or run it overnight | | A random detergent tablet | White spots despite a completed cycle | Choose a tablet formulated for hard water | | Price as the only criterion | Lower value despite the lower price | Weigh price against capacity and buyer reviews together | ## A model that avoids these mistakes from the start If you want an example of a model that balances capacity, price, and reviews without falling into any of these traps, the **Midea 12-Place-Setting Dishwasher (7 Programs)** shows it well: 12 place settings covers a family of four or more in one load, at roughly ≈ 1,049 SAR it's the lowest price among the full-size units in its category, and dozens of buyer reviews on Amazon.sa back up the consistency of its results. We won't hide the honest trade-off: it's a genuine full-size unit, so it needs a proper water and drain connection like any comparable machine, which is a real installation commitment you should confirm before ordering. That's why it tops our [guide to the best dishwasher in Saudi Arabia](/en-sa/best/best-dishwasher/).

Avoiding these five mistakes simply gets you to a model that fits how you actually use it, not the cheapest or flashiest option on the page.
