A dishwasher that won't drain, leaves dishes dirty, or leaks onto the kitchen floor can throw off an entire household's routine. At washingmachinerepairinnairobi.co.ke, we handle dishwasher repair for homes and offices across Nairobi, diagnosing and fixing everything from simple blockages to major mechanical failures. This guide walks through the most common dishwasher faults we see, what causes them, and what it typically costs to get your machine running properly again.
Why Dishwashers Break Down
Dishwashers work harder than most people realize, cycling hot water, detergent, and moving parts through multiple wash and rinse stages several times a day in busy households. Hard water common in many parts of Nairobi accelerates mineral buildup on heating elements and spray arms, while grease and food particles gradually clog filters and drain pumps. Most dishwasher repair calls we receive trace back to one of a handful of recurring issues, which is why a systematic diagnostic approach matters more than guesswork.
Dishwasher Not Draining
One of the most frequent reasons households book a dishwasher repair is standing water left in the bottom of the machine after a cycle finishes. This is almost always caused by a clogged filter, a blocked drain hose, or a faulty drain pump. Food debris and grease build up in the filter basket over time, restricting water flow until the pump can no longer clear the basin properly. Our technicians remove and clean the filter assembly, check the drain hose for kinks or blockages, and test the pump motor to confirm it's cycling correctly before returning the machine to service.
Dishes Coming Out Dirty
If dishes emerge from a full cycle still coated in food residue, the problem is usually one of several things: clogged spray arm nozzles, a failing wash pump, incorrect loading blocking water flow, or worn-out detergent dispensers that aren't releasing properly. This type of dishwasher repair often starts with a simple inspection of the spray arms, since mineral deposits and food particles frequently block the small holes responsible for distributing water evenly across the dishes. We also check water inlet valves, since insufficient water pressure entering the machine can leave dishes only partially cleaned.
Leaking Dishwashers
A leaking dishwasher is one of the more urgent dishwasher repair requests we receive, since water damage to flooring and cabinetry can become costly if left unaddressed. Common causes include a worn door gasket that no longer seals properly, a cracked or loose water inlet valve, an overfilled detergent dispenser causing excess suds, or a damaged tub that has developed a hairline crack. Our technicians run the machine through a diagnostic cycle to pinpoint exactly where water is escaping before recommending a repair.
Dishwasher Not Starting
When a dishwasher won't power on at all, the fault typically lies with the door latch switch, the control board, or the power supply itself. Many modern dishwashers include a safety interlock that prevents the machine from running unless the door is fully latched, so a worn or misaligned latch is often the simplest explanation. For this type of dishwasher repair, we test the door switch, inspect the control board for burnt components, and verify the unit is receiving stable power before replacing any parts.
Unusual Noises During Operation
Grinding, buzzing, or knocking sounds during a cycle usually point to a foreign object lodged in the pump, a worn wash pump bearing, or a spray arm hitting against dishes that have been loaded incorrectly. This category of dishwasher repair is generally straightforward once the machine is opened up, though a bearing replacement can take longer if the part isn't immediately available. We advise clients to stop the cycle and switch off the machine if grinding noises appear, since continued use can cause further internal damage.
Our Repair Process
Every dishwasher repair we carry out starts with a full diagnostic rather than replacing parts based on assumption. Our technicians run a test cycle, check error codes on digital models, inspect filters, hoses, and seals, and test electrical components including the control board and door switch. Once the fault is confirmed, we explain the issue and cost clearly before starting any repair work, so there are no surprises on the final bill.

What Our Clients Say
"Our dishwasher had been leaving a puddle on the kitchen floor after every cycle for weeks. The technician traced it to a worn door seal, replaced it within an hour, and it hasn't leaked since." — Homeowner, Runda
Frequently Asked Questions
1. Why is my dishwasher leaving water at the bottom after a cycle? This is usually caused by a clogged filter, blocked drain hose, or a faulty drain pump preventing proper drainage.
2. Why are my dishes still dirty after a full wash cycle? Blocked spray arm nozzles, low water pressure, or an overloaded rack are the most common culprits behind poor cleaning results.
3. Is a leaking dishwasher dangerous to keep using? It can lead to water damage to flooring and cabinetry, so it's best to stop using the machine and book a repair as soon as leaking is noticed.
4. How often should a dishwasher be serviced to avoid breakdowns? Cleaning the filter monthly and booking a professional service every six to twelve months significantly reduces the chance of major faults developing.
5. Is it worth repairing an older dishwasher or should I replace it? If the unit is under seven years old and the repair cost is reasonable relative to a new machine, repair is usually the better value. We give an honest recommendation after diagnosis.
