Omega OFI101XA Dishwasher Specs & Fit Guide

Updated 6 November 2026 · Standard formula, shown below

The Omega OFI101XA is a 60cm freestanding dishwasher with a 13-place-setting capacity, an A+ energy rating, and a stainless-steel finish designed to fit standard UK kitchen openings. This guide covers its key specifications, installation fit, and practical owner guidance so you can confirm compatibility and use it correctly.

Key Specifications at a Glance

Before measuring your space, here are the core numbers that define the OFI101XA. These figures come from the standard published specification for this model and are typical for a full-size freestanding dishwasher.

Dimensions: 85cm (H) x 60cm (W) x 60cm (D) — this is the standard 60/60 size for UK kitchens. Depth is measured to the front of the door, not including handles or protruding controls.
Capacity: 13 place settings, which suits a household of 4–5 people or a family that cooks daily.
Energy rating: A+ on the older EU energy label scale. This model predates the newer A–G re-scaling, so an A+ rating is roughly equivalent to a C or D under the current system.
Annual energy consumption: Approximately 290 kWh per year based on the standard 280-cycle test.
Water consumption per cycle: Around 11–12 litres on the eco programme, which is average for this class.
Noise level: 49 dB(A) — audible but not disruptive; normal conversation is about 60 dB.
Programmes: Typically includes Eco, Intensive, Normal, Quick (around 30 minutes), and a soak or pre-wash option. Exact programme names vary by control panel revision.
Finish: Stainless steel (the “XA” in the model number usually denotes this metallic finish).

Physical Fit: Will It Slot Into Your Kitchen?

The most common question from owners is whether this dishwasher will fit an existing gap. The OFI101XA is a freestanding model, meaning it has its own top and sides and is not designed to be built under a worktop without a decor panel kit.

Measure the opening width first. The dishwasher is 60cm wide, but you need a gap of at least 60.5–61cm to slide it in without forcing the cabinet sides. Height is less critical for freestanding models because the feet are adjustable. The standard height of 85cm can be raised or lowered by roughly 1.5cm in either direction using the front and rear feet. Depth is the tightest fit in many kitchens: the 60cm depth is the body only. If your cabinet opening is exactly 60cm deep, the door will not close flush because the door panel adds about 2–3cm. You typically need 63–65cm of clear depth.

Check the hose routing before pushing the unit in. The inlet hose and drain hose exit from the rear left or right corner. If your water supply and drain point are directly behind the machine, you may need to offset the dishwasher slightly or use extension hoses (keeping the total length within the manufacturer’s stated maximum, usually 2.5m for inlet and 3m for drain).

Installation Requirements and Connections

This dishwasher connects to a cold water supply only. Do not connect it to hot water unless the manual explicitly permits it; most Omega models are cold-fill. The inlet hose has a standard 3/4-inch BSP thread that fits a normal UK washing machine valve. The drain hose connects to a standpipe (the vertical pipe behind the sink) or a sink trap spigot. The drain hose must be looped up to a height of at least 40cm and no more than 100cm from the floor to prevent siphoning.

Electrical supply is a standard 13-amp plug. The unit ships with a moulded plug, so no hardwiring is needed. Ensure the socket is accessible after installation so you can unplug the machine for maintenance. Do not use an extension lead unless it is a heavy-duty 13-amp rated one; a standard multi-socket extension can overheat.

Level the machine after positioning. Use a spirit level on the top edge of the door. Adjust the front feet by turning them; the rear feet are adjusted with a screwdriver or spanner through the lower front panel. An unlevel dishwasher will leave water in the bottom of the tub and cause poor washing results.

Daily Use and Programme Selection

The control panel is a simple push-button and dial layout. You select a programme, then press Start. The quick programme is useful for lightly soiled loads but does not dry as well as the eco or intensive cycles. For everyday mixed loads, the Eco programme (usually around 3 hours) gives the best balance of cleaning and energy use, despite the long run time. The Intensive programme (around 2 hours 30 minutes) is for heavily soiled pots and pans; it uses a higher temperature and more water.

Salt and rinse aid are essential. The salt reservoir is at the bottom of the tub; fill it before first use and top up when the low-salt light comes on. Rinse aid goes in the dispenser on the inside of the door; it helps water sheet off dishes so they dry without spots. Use a dedicated dishwasher salt, not table salt, and set the water hardness level according to your local supply (usually 1–3 on the dial inside the door). If you skip salt, you will get white film on glasses and the machine may eventually scale up internally.

Common Problems and Owner Fixes

Three issues appear most often in owner discussions of this model. First, dishes not drying: this is usually because rinse aid is empty or the selected programme has no drying phase. The quick cycle does not heat the final rinse enough to dry plastic items. Second, water left in the bottom after a cycle: check the filter assembly at the base of the tub — it unscrews and can be cleaned. A blocked filter is the single most common cause of poor drainage. Third, the machine not starting: confirm the door is fully latched (the door switch is a known weak point on budget models) and that the programme dial is not left between two positions.

If the machine leaks, check the door seal for debris or damage, and verify the inlet hose connection is hand-tight plus a quarter turn. Do not overtighten with pliers as this can crack the plastic thread.

Comparing to Other 60cm Freestanding Models

Within the Omega range, the OFI101XA sits at the entry level. The main alternatives are the OFI103XA and OFI105XA, which add a digital display, delay start, and a slightly quieter motor (47 dB). The 101XA has no delay timer — if you need to set the machine to run at night, this model cannot do that. Compared to other brands, the 101XA is similar to a basic Beko or Indesit unit in terms of features. The main differentiator is the stainless steel finish at a price point where many competitors use white plastic. The internal rack layout is standard: a fold-down cup shelf, adjustable upper rack height, and a cutlery basket. The upper rack height adjustment is a simple two-position clip, not a continuous ratchet.

Owner Guidance: Loading and Maintenance Tips

To get the best results from this machine, load it deliberately. Face heavily soiled surfaces toward the centre spray arm. Do not block the spray arm rotation with tall items in the lower basket. Place plastic items on the top rack only, as the lower rack’s intensive zone can melt them. The cutlery basket has a handle; hold it by the handle when emptying to avoid cutting yourself on knives.

Clean the filter after every 10–15 cycles. Pull out the lower rack, twist the cylindrical filter assembly counterclockwise, rinse it under the tap, and replace. Wipe the door seal monthly with a damp cloth. Run a maintenance cycle with a dishwasher cleaner (or a cup of white vinegar in an empty machine) every three months to remove grease and limescale. This is not a self-cleaning model, so this manual maintenance is necessary for odour control.

Frequently Asked Questions

Will this dishwasher fit under my worktop? It will fit under a standard 90cm-high worktop, but you must remove the top panel or use the height-adjustable feet. The machine is 85cm tall with feet at mid-range, so it fits under a 90cm worktop with about 5cm of clearance. It is not a built-under model, so the top and sides will be visible unless you install it in a freestanding gap.

Can I connect it to hot water? No. The manual specifies cold water connection only. Connecting hot water will damage the inlet valve and may void the warranty. The machine heats its own water internally.

Why does my cutlery come out with spots? Spots are usually hard water minerals. Increase the water hardness setting on the dial inside the door, and ensure rinse aid is topped up. If you are in a very hard water area (above 300 ppm), you may need to use a rinse aid brand with a higher concentration.

Is the stainless steel finish prone to fingerprints? Yes, the standard brushed stainless finish shows fingerprints more than white or black. Wipe with a microfibre cloth and a small amount of stainless steel cleaner, following the grain direction. Do not use abrasive pads.

How long is the warranty? Omega typically offers a 1-year parts and labour warranty on this model, with an optional extended warranty available at point of sale. Check your specific retailer’s terms, as some offer longer coverage.

Can I replace the door panel to match my kitchen? No. This is a freestanding model with an integrated stainless steel door. It is not designed to accept a custom decor panel. If you need a fully integrated dishwasher, you must look at a different model.
