How to Clean and Maintain Your Tricity Bendix Dishwasher

What Tricity Bendix dishwashers are and where to find manuals

Tricity Bendix is a British appliance brand that made dishwashers from the 1960s through the early 2000s. If you own one, you likely have an older model — the brand stopped producing new dishwashers years ago, though many units still run reliably in homes across the UK and Europe. Finding the original manual can be difficult because Tricity Bendix no longer operates as an independent company, and many product pages have disappeared from the internet.

Your best sources for a Tricity Bendix dishwasher manual are archived appliance websites, eBay listings (where sellers sometimes photograph manuals), and general dishwasher repair forums where users post scans of older documentation. If you know your model number — usually found on a sticker inside the door frame or on the side panel — you can search that number directly on archive sites. Many older Tricity Bendix models follow similar logic to other European dishwashers of that era, so a manual for a comparable brand from the same period may help you understand the basics of your machine.

Key Takeaways

• Tricity Bendix dishwashers are older machines no longer in production, so finding the original manual requires searching archived sites or repair forums rather than the manufacturer's website.
• Your model number, found on a sticker inside the door or on the side panel, is essential for tracking down documentation specific to your machine.
• Regular cleaning of the filter, spray arms, and door seals keeps your Tricity Bendix running efficiently and prevents odors and poor wash performance.
• Hard water deposits and detergent buildup are the most common problems in older dishwashers and can be managed with rinse aid and occasional deep cleaning.
• If your machine stops draining or heating, check the filter and drain hose first — these are the parts most likely to fail in an older model.

How to locate and clean the filter in your Tricity Bendix

The filter is the part of your dishwasher that traps food particles and prevents them from recirculating onto your dishes. In most Tricity Bendix models, the filter sits at the bottom of the wash chamber, usually in the center or toward the back. To access it, remove the bottom rack and look for a cylindrical or basket-shaped component — it may have a handle or knob on top.

Unscrew or unclip the filter (the method depends on your model) and rinse it under warm running water. Use an old toothbrush to scrub away any stuck-on food, grease, or mineral deposits. If the filter is very dirty or smells, soak it in warm water with a tablespoon of white vinegar for 15 to 20 minutes before scrubbing. Rinse thoroughly and replace it, making sure it sits flush and is secured properly — a loose filter will allow debris back into the wash chamber and reduce cleaning power.

Clean the filter every two to four weeks if you run your dishwasher regularly. If you notice poor wash results, standing water at the bottom of the machine, or a musty smell, check the filter first — it is often the culprit.

Cleaning the spray arms and water jets

Spray arms are the rotating parts that spray water onto your dishes during the wash cycle. Over time, mineral deposits from hard water can clog the small holes in the spray arms, reducing water pressure and leaving dishes dirty. Most Tricity Bendix models have one or two spray arms — one at the bottom and sometimes one at the top.

Remove the bottom rack to access the lower spray arm. Look for a clip or bolt holding it in place, unscrew or unclip it, and lift the arm out. Hold it up to a light and look through each hole — if you see white or brown crusty buildup, the arm needs cleaning. Soak the spray arm in warm water with white vinegar for 30 minutes, then use a thin wire, toothpick, or old toothbrush to clear each hole. Rinse under running water and reinstall it, making sure it spins freely.

If your dishwasher has an upper spray arm (accessible by removing the top rack), clean it the same way. After reinstalling both arms, run an empty cycle to check that they rotate smoothly and spray water evenly.

Managing hard water deposits and odors

Hard water leaves white, chalky deposits on dishes and inside the machine. Older Tricity Bendix dishwashers are especially prone to this because they lack some of the water-softening features found in modern machines. The solution is rinse aid, a liquid that helps water sheet off dishes and reduces spotting and buildup.

Most Tricity Bendix models have a rinse aid dispenser — a small compartment, usually near the detergent dispenser, marked with a water droplet symbol. Open it and fill it with commercial rinse aid (brands like Finish or Ecos are widely available). The dispenser has a dial or setting that controls how much rinse aid is released per cycle; start at the middle setting and adjust based on results. If you still see spots, increase the setting; if you see streaks or residue, decrease it.

For stubborn mineral buildup inside the machine, run an empty cycle with a cup of white vinegar placed in the bottom of the wash chamber. The vinegar will dissolve deposits on the walls, heating element, and internal parts. Do this once every two to three months if you have hard water, or once every six months if your water is soft.

Odors in older dishwashers usually come from trapped food particles or mold in the door seal. Wipe the rubber seal around the door with a damp cloth and a little white vinegar, paying attention to the creases where debris collects. If the smell persists after cleaning the filter and seal, run the vinegar cycle described above.

Checking and cleaning the drain hose

The drain hose carries dirty water out of your dishwasher and into your sink or waste pipe. If water pools at the bottom of the machine or drains very slowly, the hose may be clogged or kinked. To inspect it, you will need to access the area behind or under your dishwasher — this usually means pulling the machine out slightly or removing the front panel (consult your manual for the exact steps if you have it).

Look for the hose running from the bottom of the machine to the sink drain or waste outlet. Check that it is not bent sharply or pinched. If it appears kinked, straighten it gently. If it looks clear but water is still not draining, disconnect the hose at both ends (have a bucket ready to catch water) and flush it with warm water from a tap. If water does not flow freely, use a plumbing snake or a length of flexible wire to push out the blockage. Reconnect the hose securely and test the machine.

If the hose is cracked or leaking, it will need to be replaced — this is a job best left to a repair technician, as it involves working with the machine's internal plumbing.

Organizing your load and using the right detergent

Older Tricity Bendix dishwashers work best when loaded thoughtfully. Place plates and bowls upright in the lower rack, facing the spray arm. Put glasses and cups in the upper rack, tilted slightly so water can drain out. Avoid blocking the spray arms with large items — they need to rotate freely to reach all surfaces.

Use a detergent formulated for your water hardness. Powder detergent is generally more effective in hard water than tablets, because you can adjust the amount based on how much buildup you are seeing. Start with the amount recommended on the package, then increase or decrease slightly depending on results. If you use tablets, choose ones designed for hard water or add a separate water softener product.

Run your dishwasher only when it is full — this saves water and energy, and ensures the detergent concentration is strong enough to clean effectively. If you run it half-empty frequently, increase the detergent slightly to compensate.

When to call a repair technician

Some problems in a Tricity Bendix dishwasher are beyond routine maintenance. If the machine does not heat water (dishes come out cold and wet), the heating element may have failed. If it does not drain at all even after you have cleaned the filter and hose, the pump may be broken. If it leaks from the door seal despite cleaning, the seal itself may need replacement. These repairs require opening the machine and working with electrical or mechanical components — work best handled by someone with appliance repair experience.

Because Tricity Bendix is no longer in business, finding replacement parts can be challenging. Some parts are available through specialist appliance suppliers or online marketplaces, but availability varies by model. Before investing in repairs, weigh the cost against the age and condition of your machine — sometimes an older dishwasher reaches a point where repair costs more than replacement.

Frequently Asked Questions

Where can I find a manual for my Tricity Bendix dishwasher?

Search archive sites like the Internet Archive (archive.org) using your model number. Appliance repair forums and eBay listings sometimes have scanned manuals. If you cannot find your exact model, look for manuals from similar European dishwashers from the same era — the basic operation is usually very similar.

My Tricity Bendix is leaving white spots on dishes — what should I do?

White spots are mineral deposits from hard water. Fill the rinse aid dispenser and set it to a higher level. Run an empty cycle with a cup of white vinegar in the bottom to dissolve buildup inside the machine. If spots persist, you may need to increase the rinse aid setting further or switch to a detergent designed for hard water.

The dishwasher smells musty — how do I fix it?

Clean the filter thoroughly and wipe the door seal with a damp cloth and white vinegar, paying attention to creases. Run an empty cycle with a cup of white vinegar in the wash chamber. If the smell returns quickly, it may indicate mold growth inside the machine, which sometimes requires professional cleaning or repair.

Can I use modern dishwasher tablets in my older Tricity Bendix?

Yes, modern tablets work in older machines, though powder detergent often performs better in hard water because you can adjust the amount. If you use tablets, choose ones formulated for hard water or add a separate rinse aid product to reduce spotting.

My dishwasher is not draining — what should I check first?

Remove and clean the filter at the bottom of the wash chamber — trapped food is the most common cause of poor drainage. Check the drain hose for kinks or blockages. If water still pools after cleaning both, the drain pump may have failed and will need professional repair.
