Every month our technicians at Appliance Repair log dozens of callouts across Nairobi, and September 2026 was no exception. From Kilimani apartments to Karen villas, dishwashers kept breaking down in strikingly predictable ways. If you're dealing with a machine that won't drain, won't heat, or won't even switch on, chances are one of our engineers has already fixed the exact same fault this month.
Below is a breakdown of the 12 most common dishwasher faults our dishwasher repair team encountered in September, what causes them, and how we resolved each one. We've also included real advice from our technicians and a cost guide so you know what to expect before you call.
Whether you're in Westlands, Lavington, Embakasi, or further out in Ruaka, hard water, power fluctuations, and heavy daily use all take a toll on dishwashers in similar ways. Understanding the warning signs early can save you a costly breakdown and, in many cases, a full replacement.
1. Clogged Drain Filter
By far the most frequent job on our books. Food particles, labels, and grease build up in the drain filter until water can no longer clear the tub, leaving standing water after every cycle.
"Nine times out of ten, a dishwasher that smells bad or leaves water pooling at the bottom just needs its filter removed and rinsed under a tap. We recommend doing this every two weeks." — Appliance Repair technician
2. Faulty Door Latch
A worn or misaligned door latch prevents the machine from starting because the safety switch never registers a proper close. We replaced dozens of latch assemblies this month, mostly on machines over five years old.
3. Heating Element Failure
Cold or greasy dishes after a full cycle almost always point to a dead heating element. This was our second most common dishwasher repair call in September, particularly among Bosch and Samsung units.
"If your plates come out cold and your glasses look cloudy, don't assume it's the detergent. Test the heating element before buying anything new."
4. Blocked Spray Arms
Mineral deposits and food debris clog the small holes in the spray arms, so water can't reach the upper rack. A quick soak in warm vinegar water usually restores full pressure.
5. Worn Door Seal (Gasket)
Leaking water around the base of the dishwasher is typically a torn or hardened rubber gasket. Nairobi's hard water accelerates this wear considerably, especially in Nairobi's older estates like South B and Buruburu.
6. Drain Pump Failure
When a dishwasher fills but never drains, the drain pump motor has usually seized or burned out. This is one of the pricier fixes on our list, but replacing the pump is far cheaper than a new machine.
"A humming noise with no water movement is a classic drain pump symptom. Switch the machine off immediately to avoid burning out the motor further."
7. Faulty Control Board
Electronic control boards fail after power surges, which are common during Nairobi's rainy season. Symptoms include flashing lights, cycles that stop mid-way, or a unit that won't respond to any button. We strongly recommend a surge protector for any high-value kitchen appliance, as it's one of the easiest ways to avoid this fault altogether.
8. Inlet Valve Malfunction
If your dishwasher won't fill with water at all, the water inlet valve is the usual suspect. We see this fault spike whenever clients report inconsistent mains water pressure, which is common across several Nairobi suburbs.
9. Detergent Dispenser Stuck
A dispenser that won't pop open mid-cycle leaves dishes coated in dried soap. Grease buildup around the spring-loaded latch is almost always the cause, and it's one of the simplest dishwasher repair jobs we handle.
"Wipe down the dispenser door every few washes. It's a thirty-second habit that prevents one of our most common callouts."
10. Float Switch Stuck
The float switch stops the machine from overfilling. When it sticks in the "up" position, the dishwasher won't fill at all; stuck "down," it overflows onto your kitchen floor.
11. Noisy Motor Bearings
A loud grinding or squealing sound during the wash cycle usually means the wash motor's bearings are worn out. We replaced or serviced several motors this month on units that were six-plus years old. Left unaddressed, worn bearings eventually cause the motor to seize completely, turning an affordable service job into a full motor replacement.
12. Broken Rack Wheels
Not a functional fault, but a frequent complaint. Cracked or missing rack wheels make loading dishes frustrating and can eventually damage the door seal if racks drag unevenly.
"Small parts like rack wheels are cheap to replace and often overlooked. Fixing them now saves you a bigger repair bill later."
