E18, F21, E23 or F16 on the display? We repair the full Siemens iQ range at your home across Dubai, Sharjah, Abu Dhabi & Ajman β with the price agreed before any work begins.
UNITECH HOME BUILDING MAINTENANCE L.L.C is an independent repair company. We are not an authorized Siemens service centre and we are not affiliated with or endorsed by Siemens or the BSH group. The Siemens name is used here only to identify the machines we repair.
Independent third-party repair notice: we are not an authorized service center, dealer or affiliate of Siemens. Siemens and all related model names are trademarks of their respective owner and are used on this page for identification purposes only.

Siemens and Bosch are both made by the BSH group, and equivalent models are built on shared platforms. That is not marketing detail β it has a direct, practical effect on what it costs to keep a Siemens machine running in the UAE.
Because the platforms overlap, the fault codes are effectively the same set, the service procedures are closely related, and a great many components are similar or directly interchangeable between equivalent Bosch and Siemens models. In a market where parts availability for premium European brands can be the real bottleneck, that roughly doubles the pool a technician can draw a correct part from. Repairs that would otherwise mean a long wait for a single-source component are often completed the same day.
What is genuinely Siemens-specific sits mostly on the control side β the iQ range structure, the sensing systems and the programme logic. So we diagnose the mechanics with the full BSH picture in mind, and treat the electronics as Siemens' own.
Siemens uses the BSH code family, so these will look familiar to anyone who has owned a Bosch machine.
Drain fault. Water not pumped out in time. Pump filter, drain hose or drain pump β usually the filter.
Fill timeout. Not taking water fast enough. Tap, kinked hose, blocked inlet filter or inlet valve.
Aquastop triggered. Water in the base tray. A genuine internal leak β treat as urgent.
Motor fault. Carbon brushes on brushed motors, tacho coil, motor wiring or the control module.
Door not closed. Door not latching or the interlock not confirming. Often the lock or a worn catch.
Drum not turning. Motor not rotating the drum β jammed drum, drive fault or motor failure.
Heating timeout. Water not reaching temperature β heating element or NTC sensor.
Sensor fault. NTC temperature sensor out of range or open circuit.
Water level too high. Overfilling β inlet valve stuck open or pressure system misreading.
Door lock system. Interlock not engaging or releasing correctly β lock or its control circuit.
Module fault. Control module or function error, always tested before any board is replaced.
Motor error. Motor circuit fault reported by the module, checked alongside brushes and wiring.
Code meanings vary slightly between Siemens generations and iQ ranges. Send us a photo of the display and the model number and we will confirm what yours points to.

Siemens machines are well built and fail in a predictable pattern, which keeps most repairs quick:
The full iQ line-up and the older generations still working in UAE homes.
The volume range in UAE apartments. Pumps, door locks, elements and sensors.
Mid-range machines with more sensing. Diagnosed on sensor readings as much as mechanics.
Top specification with the most electronics β module and sensor diagnosis matters most here.
No carbon brushes, so a different fault profile from the older brushed machines.
Machines with base-tray and inlet-hose leak protection, tested as part of every diagnosis.
Machines behind cabinet fronts, removed on floor protection and refitted flush.
Combined units β heating, condenser and moisture sensor faults on the drying side.
Siemens machines running long daily cycles in laundries, salons and staff accommodation.
We are not an authorized Siemens service centre. UNITECH HOME BUILDING MAINTENANCE L.L.C is a private, independent repair company holding UAE trade licence number 134585. We have no affiliation with Siemens or the BSH group, no endorsement from them, and no authorization to carry out warranty work on their behalf.
If your washing machine is still within its manufacturer warranty period, contact Siemens or the retailer you bought it from first β a repair carried out by an independent company can affect that cover, and you may be entitled to a free repair you would otherwise pay us for. Tell us how old the machine is and we will give you an honest view.
The spare parts we fit are high-quality OEM-standard compatible components. Where a BSH-equivalent part is a correct match for your model, we will tell you that is what is being used, along with the cost, before it goes in.
Siemens codes vary by iQ range and generation, so the model number matters as much as the code.
Pump, brushes, tacho, heater, NTC sensor and door lock tested in order before anything is condemned.
Exact price for parts and labour before dismantling. Nothing proceeds without your approval.
Common BSH pumps, brushes and door locks are carried on the van for single-visit repairs.
Complete cycle run, heating and spin confirmed, machine re-levelled before we leave.

No. We are UNITECH HOME BUILDING MAINTENANCE L.L.C, a private independent repair company licensed in the UAE under trade licence 134585. We are not affiliated with, endorsed by, or an authorized service provider of Siemens or the BSH group. We repair Siemens machines as an independent third party and use the brand name only to identify the machines we work on.
They share a great deal. Both are made by the BSH group and equivalent models are built on common platforms, which means the fault code sets overlap almost completely and many components are similar or directly interchangeable. It is genuinely good news for UAE owners, because it widens parts availability and keeps repair costs down. The differences are mostly in the control interface, the programme set and the trim.
E18 is a drain fault β the machine did not pump the water out in the expected time. The usual cause is the pump filter behind the small flap at the bottom front, which collects coins, hair clips and lint. After that it is a blocked drain hose or a failed drain pump. It is one of the cheaper Siemens repairs, and quite often the filter simply needs clearing.
That is the Aquastop leak protection. There is a float switch in the base tray, and when water collects there the machine shuts down and refuses to run so it does not flood the room. It means there is a real leak inside β a hose, the sump, the pump housing or the tub seal. It should be attended to promptly, particularly in an apartment above another home.
The iQ number indicates the specification level rather than a different machine architecture. Higher iQ ranges add features such as more advanced sensing, quieter brushless motors and automatic detergent dosing. From a repair point of view the core mechanics are closely related across the ranges, but the higher models carry more electronics, so sensor and module diagnosis matters more on those.
If your machine is still within its manufacturer warranty period, contact Siemens or your retailer first, because a repair by any third party can affect that cover. Our service is intended for out-of-warranty machines, or where the owner has chosen to use an independent repairer. Tell us the age of the machine and we will give you an honest view on which route makes more sense.
Photograph the display and the model sticker and send both on WhatsApp. We will tell you what the fault points to before you commit to a visit.
Siemens model numbers usually start with WM and are printed on a sticker inside the door rim. With that and the code, we can normally diagnose before arriving.
