Fix or Replace Dishwasher: Quick Guide to Making the Right Call

Your dishwasher just stopped cleaning dishes, and you’re stuck wondering whether a repair will do or if it’s time for a brand‑new unit. The good news is you don’t need a PhD in appliances to figure it out. With a few simple checks and a clear cost look‑up, you can decide fast and avoid wasting money.

Spot the Common Faults First

Most dishwasher problems fall into three buckets: drainage, cleaning power, and electronics. If water won’t drain, a clogged filter or a worn pump is usually to blame. A weak wash often means spray arms are blocked, the detergent dispenser isn’t opening, or the heating element has failed. When the control panel freezes or shows error codes, the issue is often a faulty sensor or a loose wiring connection.

Take a look at the filter and spray arms. Remove them, rinse off food debris, and spin them by hand. If they move freely, the blockage is probably elsewhere. Next, listen for the pump’s hum when the cycle starts – a silent pump usually needs replacement.

Cost Comparison: Repair vs. Replace

Repair costs vary by part. A new filter or a set of spray arms can be under £30. A pump or heating element replacement usually runs between £80 and £150, parts plus labour. If the control board is the culprit, you’re looking at £150‑£250. Compare that to the price of a new dishwasher: entry‑level models start around £300, mid‑range around £500, and premium units can exceed £1,000.

As a rule of thumb, if the repair cost is more than half the price of a comparable new machine, it’s smarter to replace. Also consider the age of the appliance. Dishwashers typically last 8‑12 years. If yours is over 10 years old and you’ve already spent on a couple of fixes, a new, energy‑efficient model will save on water and electricity bills.

Don’t forget warranties. A fresh dishwasher often comes with a two‑year guarantee, covering parts and labour. That peace of mind can tip the scales toward replacement, especially if you’re prone to using the machine heavily.

Bottom line: run a quick visual check, estimate the part price, and weigh it against the cost of a new unit. If the numbers line up, go for a repair. If not, start shopping for a replacement that fits your budget and space.
