1. Types of Dishwashers We Repair

We service all types of dishwashers used in homes, restaurants, hotels, and commercial kitchens across Nairobi.

2. Common Dishwasher Faults We Fix

If your dishwasher is showing an error code or simply not performing, here are the most common issues our technicians resolve daily in Nairobi.

a) Dishwasher Not Draining

Water sitting at the bottom of the dishwasher after a cycle is one of the most common calls we receive in Nairobi. It almost always has a straightforward mechanical cause.

Internal inspection — spray arms, filter, and wash pump

b) Dishwasher Not Cleaning Dishes Properly

Dishes come out dirty, greasy, or with food still stuck on them despite a full wash cycle.

c) Dishwasher Leaking Water

Water on the kitchen floor is an urgent fault — prolonged leaking damages flooring, cabinets, and can create an electrical hazard.

• Damaged door seal / gasket — the rubber seal around the door has split or warped; replace the door gasket
• Leaking door latch — door not closing fully allows water to spray out; adjust or replace latch
• Cracked spray arm — water sprays sideways instead of upwards; replace the spray arm
• Loose or damaged water inlet hose — connection at back of machine leaking; tighten or replace hose
• Faulty water inlet valve — valve not shutting off properly, causing overflow; replace valve
• Too much detergent / wrong detergent — excessive foam causes overflow through the door; use correct dosage
• Cracked tub or wash arm housing — rare but requires component replacement

d) Dishwasher Not Filling with Water

• Water inlet valve failed — solenoid valve not opening to let water in; test and replace
• Kinked or pinched water supply hose — check the hose at the back of the unit
• Float switch stuck in "full" position — the float assembly tells the machine the tub is full when it isn't; clean or replace float
• Water pressure too low — minimum 0.5 bar required; check home water pressure
• Control board not sending signal to inlet valve — board fault requires diagnosis and possible replacement

e) Door Not Closing or Latching

• Broken door latch assembly — the most common cause; latch hook or catch has broken; replace latch
• Worn or stretched door hinges — door hangs low and won't align with the latch; adjust or replace hinges
• Faulty door latch switch — machine won't start even if door is closed; the switch that confirms closure has failed
• Warped door seal — thick seal prevents door from fully closing; replace the gasket

f) Dishes Not Drying

• Heating element failed — the element that heats air during the dry cycle has burnt out; replace element
• Rinse aid dispenser empty or faulty — rinse aid is essential for drying; refill or replace dispenser
• Thermostat fault — not reaching the correct temperature for drying; test and replace thermostat
• Fan motor failed — on models with fan-assisted drying; replace fan motor

g) Bad Smell from Dishwasher

• Dirty or clogged filter — food particles trapped in filter rot and smell; clean filter monthly
• Blocked drain hose — stagnant water trapped in hose creates odour; flush and clear hose
• Mould inside door seal — dark mould grows in the rubber gasket folds; clean with white vinegar
• Dirty spray arms — food trapped inside spray arm holes; remove and clean thoroughly

h) Noisy Dishwasher

• Grinding noise — food debris or broken glass in the pump; clear debris, check pump for damage
• Thumping or banging — spray arm hitting dishes or tall items in rack; reload dishes to allow arm to spin freely
• Humming or buzzing — normal during wash cycle, but loud hum indicates a failing pump motor
• Rattling — loose cutlery or small items not secured in basket; secure items before running cycle

3. How a Dishwasher Works

Understanding how your dishwasher works helps explain why faults occur and what our technicians look for during diagnosis.

At the start of a cycle, the water inlet valve opens to let in hot water from your supply. The circulation pump pressurises this water and forces it up through the spray arms, which rotate and spray water over the dishes. Detergent is released from the dispenser mid-cycle. After washing, the drain pump removes dirty water, and the heating element (or fan, depending on model) dries the dishes.

All of this is controlled by the control board, which sequences each stage of the cycle according to the programme selected. A fault in any one component can stop the whole machine — or cause it to run a cycle without properly cleaning or draining.

4. Dishwasher Brands We Repair in Nairobi

We repair all dishwasher brands available in Kenya. Here are the most common brands and their known weak points.

5. How We Diagnose Your Dishwasher

Every Quelle Technologies technician follows the same structured diagnostic process — no guesswork, no unnecessary parts replaced.

1. Visual Inspection
   Check for obvious damage — cracked door seal, blocked filter, visible leaks, or burnt marks.
2. Power CheckConfirm 240V at socket. Check if the machine responds to programme selection. Note any error codes on the display.
3. Water Supply CheckConfirm the water supply tap is open and hose is not kinked. Test water pressure at the inlet.
4. Filter & Spray Arm InspectionRemove and inspect filter for blockages. Remove spray arms and check all holes are clear.
5. Pump TestingRun drain cycle to listen to drain pump. Run wash cycle to test circulation pump pressure and noise.
6. Electrical Component TestingTest heating element, inlet valve solenoid, door latch switch, and thermostat with a multimeter.
7. Full Cycle TestAfter repair, run a full wash cycle to confirm everything is working — draining, filling, washing, and drying — before we leave.

6. Is It Worth Repairing My Dishwasher?

In most cases, yes. Dishwashers are worth repairing when the fault is mechanical or electrical — which covers the vast majority of failures. Here's a practical guide.

We always give a clear, honest quote before starting. If the repair cost is more than 60% of the price of a new unit, we will tell you — and help you make the right decision.

7. Dishwasher Maintenance — Every 1–3 Months

Regular maintenance keeps your dishwasher cleaning effectively, smelling fresh, and lasting longer. We offer maintenance contracts for homes, restaurants, and hotels across Nairobi.

8. Tips to Extend Your Dishwasher's Life

• Clean the filter monthly. It takes 2 minutes and prevents most "not draining" and "not cleaning" faults entirely.
• Use the correct detergent and rinse aid. Regular dish soap creates too much foam and damages the pump seals over time.
• Don't overload. Overloading blocks spray arms from rotating and means water can't reach all surfaces properly.
• Scrape plates — don't pre-rinse. Scrape off solid food but leave a light residue — modern dishwasher detergent needs something to work against or it over-foams.
• Run a hot cycle regularly. Run the hottest programme at least once a week to prevent grease and bacteria buildup in the drain hose and pump.
• Leave the door slightly open after a cycle. This lets the interior dry out and prevents mould growth on the door seal.
• Use a surge protector. Power surges in Nairobi damage control boards — especially in Samsung and LG dishwashers.
• Don't ignore error codes. Error codes on the display point directly to the faulty component. Note the code and call us — it speeds up diagnosis significantly.
