A Quick Fix Guide for Owners
At DKD Vehicle Wash, we’ve spent over 40 years partnering with car wash owners across British Columbia and Alberta, providing expert repair, maintenance, and installation services. We understand that a reliable, high-performing touchless car wash is the backbone of your business. Downtime isn’t just an inconvenience—it’s lost revenue and customer frustration. While our team is always on call for a service visit, we believe in empowering owners with the knowledge to handle minor issues themselves. This quick fix guide provides an expert-level look at common touchless car wash problems, helping you minimize downtime and costly service calls.
Issue #1: Sensor Malfunctions
Focus Keyword: car wash sensor issues
Modern touchless systems rely on a complex network of sensors to detect vehicles, trigger wash cycles, and ensure safety. When a sensor fails, the entire system can stall.
Symptoms:
- The wash cycle doesn’t start when a vehicle enters the bay.
- The spray arm or other equipment stops mid-cycle.
- The machine operates inconsistently or misses parts of the vehicle.
- False starts or shutdowns.
Quick Fixes:
- Clean the Sensors: In our experience, the most common cause is simple: a dirty sensor. Dust, soap residue, or water spots can block a sensor’s line of sight. Gently wipe down all sensors with a soft cloth and a non-abrasive cleaner.
- Check Alignment: Vibration from the machinery can sometimes cause a sensor to shift. Check your system’s manual to ensure all sensors are pointed correctly and are at the proper height and angle.
- Inspect Wiring: A loose or damaged wire can disrupt a sensor’s signal. Visually inspect the wiring and connections for any signs of wear, fraying, or disconnection.
If these simple steps don’t resolve the issue, it may indicate a more complex car wash electrical problem or a faulty sensor that requires a professional’s diagnosis.
Issue #2: Low or Inconsistent Water Pressure
Focus Keyword: car wash pump repair
Touchless car washes depend on high-pressure water to clean vehicles effectively. A drop in pressure can result in a poor wash, leaving customers with streaky or dirty cars.
Symptoms:
- Weak water jets.
- Soaps and waxes aren’t rinsing off properly.
- Unusual noises coming from the pump or equipment.
- The machine takes longer than usual to complete a cycle.
Quick Fixes:
- Inspect Nozzles and Filters: Clogged nozzles, often caused by hard water deposits or debris, can severely restrict water flow. Clean or replace any clogged nozzles and check your water filters for buildup.
- Check Water Supply: Ensure that the main water supply valve is fully open and that there are no kinks or blockages in the supply lines. Verify that your water tanks have sufficient water levels.
- Examine the Pump: While a full car wash pump repair is a job for our qualified technicians, a quick visual inspection can sometimes reveal an obvious problem like a loose connection or a visible leak.
If your water pressure issue persists, the problem likely lies within the pump itself—a complex system that requires the expertise of a Red Seal certified technician to diagnose and repair safely.

Issue #3: Electrical and Software Glitches
Focus Keyword: car wash electrical problems
From unresponsive payment terminals to unexpected shutdowns, electrical and software issues can bring your operation to a sudden halt.
Symptoms:
- Wash cycles suddenly stop.
- Control panels freeze or display error codes.
- Payment terminals are not processing transactions.
- Lights or other electrical components flicker or fail.
Quick Fixes:
- Power Cycle the System: The classic “turn it off and on again” solution is often effective for minor software glitches. Follow your system’s manual for a proper reboot procedure.
- Check Breakers and Fuses: A tripped breaker or a blown fuse can cause an entire section of your wash to fail. Locate your electrical panel and check for any tripped breakers.
- Inspect for Loose Wiring: Check the control panel and all visible wiring for any loose connections. A simple re-seating of a connector can sometimes resolve an issue.
For more serious car wash electrical problems, such as faulty wiring or a failing motor, it is crucial to call a professional. Working with high-voltage equipment is dangerous and should only be handled by a licensed electrician or a certified car wash technician.
