Tall wine glasses in the dishwasher: use the adjustable upper rack

Many households know the frustrating issue: attractive tall glasses need to go in the dishwasher, but there simply is not enough room in the upper rack. The result is improvised loading, washing by hand or precariously wedging them in at an angle. Yet modern machines have long included a solution that surprisingly few people use.

Adjustable upper rack: the hidden space-maker

The upper rack in many current dishwashers can be adjusted for height. Usually, this involves a small lever on either side or rails with locking positions. Once used correctly, it creates sufficient space even for tall white or red wine glasses.

“With a quick adjustment to the upper rack, you can often gain several centimetres of height – exactly what tall glasses have been missing.”

Rather than positioning glasses at an awkward angle, the entire rack is lowered. This lets the stems stand upright, makes the glass less likely to wobble and significantly reduces the chance of cracks.

How to check whether your upper rack is adjustable

People who have owned their machine for a long time often overlook what it can do. This quick check is worthwhile:

• Pull the rack fully out and inspect the side sections.
• Look for levers, tabs or buttons at the sides of the rack.
• Check the rails for markings, usually showing two or three height settings.
• If unsure, consult the instruction manual or look up the model online.

For many models from Bosch, Siemens, Neff, Bauknecht and other brands, a height-adjustable upper rack has long been standard equipment. It may be referred to as “RackMatic” or simply a “3-level height-adjustable upper rack”.

Step by step: fitting tall glasses into the upper rack

Once you know the right procedure, it permanently changes how you load the dishwasher. Here is how to do it reliably:

1. Empty the dishwasher completely, or at least clear the upper rack.
2. Pull out the upper rack as far as it will go.
3. Press or lift the side levers or catches at the same time.
4. Carefully guide the rack into the lower position until it clicks audibly into place.
5. Test the height using one of the tallest glasses: does it fit standing freely?
6. Place glasses with some space between them so that they do not touch.

One point to bear in mind: lowering the upper rack can sometimes leave less clearance above pots or plates in the lower rack. If you need to wash lots of large pots, simply raise the rack again afterwards, allowing the machine to be adapted flexibly to the load.

Why the upper rack is ideal for wine glasses

Many people routinely put tall glasses in the lower rack, although this is rarely the best option. The upper rack offers several advantages:

• Less powerful water jets, reducing the risk of breakage
• Better supports for stems, cups and smaller items
• Often fold-down grids that provide additional stability for glasses
• Greater separation from heavy pots and pans that may shift during the wash cycle

Many manufacturers now equip the upper rack specifically with glass zones, including soft silicone supports, folding brackets or dedicated inserts. Using these noticeably reduces the risk of scratches and hairline cracks.

How to position wine glasses correctly in the dishwasher

How glasses are placed in the rack determines whether they come out clean and intact, or looking dull and marked.

Common loading mistakes

Three classic incorrect positions are particularly common:

• Glasses lean into one another and repeatedly knock together during the cycle.
• The base of the glass sits directly in a strong water jet, increasing the strain on it.
• The bowl is angled so steeply that wash water cannot drain properly, leaving marks behind.

Instead, position the stems neatly in a row on the designated supports. The bases should be tilted slightly so water can run off, but not so much that the centre of gravity becomes unstable.

“The more securely a glass stands, the lower the risk of breakage – making the upper rack a safe parking area for delicate pieces.”

Programme selection and temperature for delicate glasses

Tall wine glasses are often made from thin crystal or at least very fine glass. The wash programme should be chosen accordingly. Many modern appliances feature:

• A gentle programme designed specifically for glasses
• Lower temperatures, usually 40 to 45 degrees
• Gentler water circulation with reduced spray pressure

If there is no dedicated glass programme, an Eco or short programme at a lower temperature is far more suitable than an intensive 70-degree programme. Over time, high heat can cloud glass and damage the material.

Goodbye water marks: keeping glasses clear

Alongside correct rack placement, dishwasher maintenance also plays a part. Anyone who repeatedly unloads cloudy glasses should check a few key settings.

Problem	Possible cause	Solution
Cloudy film	Temperature too high, aggressive detergent powder	Choose a gentle programme and try a different detergent
Noticeable water marks	Too little rinse aid or hard water	Increase the rinse aid setting and set the appliance to the correct water hardness
Fine scratches	Glasses knock against each other or metal parts	Leave more space, use supports and adjust the upper rack

Many people underestimate the importance of setting the dishwasher's water hardness correctly. If it is set too low, limescale cannot be bound sufficiently and becomes visibly deposited on glasses. It is worth checking your water supplier's information or using a simple test strip.

When wine glasses are better washed by hand

Despite all these tips, there are limits. Very expensive crystal glasses, extremely thin-walled bowls or pieces decorated with gold or platinum rims should generally not go in the machine. Manufacturers normally label these accordingly.

If in doubt, opt for traditional hand washing: lukewarm water, a mild washing-up liquid and a soft sponge, followed by polishing with a lint-free cloth. This keeps especially valuable glasses undamaged for years.

A practical everyday mix: combine machine and hand washing

For everyday use, a combination approach works well: durable everyday glasses can go into the machine without trouble when the upper rack is adjusted, while particularly delicate pieces can be washed quickly by hand. This saves time without putting favourite glasses at risk.

Anyone who regularly hosts visitors or enjoys wine evenings benefits especially from an adjustable upper rack. Tall glasses can be cleaned together in one cycle rather than spread across several loads or leaving you tired at the sink at the end.

Know the technology, make everyday life easier

Many household appliances can do more than is apparent at first glance. The adjustable upper rack in a dishwasher is one of these hidden convenience features. Once you start using it, it changes the entire loading routine: tall glasses, large mugs and even smaller vases suddenly fit without stress or risk.

When buying a new appliance, it is worth specifically looking for this feature in the technical specifications. Terms such as “height-adjustable upper rack”, “3-level adjustable” or “flexible rack system” indicate that the interior can be adapted to different everyday situations. Delicate wine glasses then stop being a special case and simply become part of the normal wash cycle.
