Ball Trough Not Kicking Out Ball WPC: Troubleshooting Guide

Introduction

In the world of WPC (Williams Pinball Controller) pinball machines, encountering issues with the ball not being kicked out of the ball trough can be frustrating. This problem can stem from various causes, including worn-out components, misaligned sensors, or software glitches. In this article, we will explore the troubleshooting process for a WPC pinball machine where the ball is not being kicked out of the ball trough. We will discuss potential causes and provide step-by-step instructions on how to diagnose and resolve the issue.

Potential Causes and Diagnosis

Worn-Out Parts

One common reason for the ball not being kicked out of the ball trough is worn-out parts. Over time, mechanical components like solenoids, switches, and other moving parts can wear down, leading to malfunction. To check if this is the cause, inspect all visible components for signs of wear or damage. If you find any worn-out parts, it might be necessary to replace them.

Misaligned Sensors

Misaligned sensors are another possible culprit. The ball trough relies on optical or mechanical sensors to detect when a ball is present and needs to be kicked out. If these sensors are misaligned or dirty, they may fail to function correctly. Carefully inspect the sensors and ensure they are aligned properly. Clean them with a soft cloth if needed. Misalignment can often be fixed by gently adjusting the sensor position.

Software Glitches

Software glitches can also affect the functionality of the ball trough. Firmware updates or corrupted settings can cause unexpected behavior. To troubleshoot this, start by checking for firmware updates from the manufacturer’s website. If an update is available, follow the installation instructions provided. Additionally, resetting the machine’s settings to factory defaults can sometimes resolve software-related issues.

Step-by-Step Troubleshooting Process

Step 1: Inspect Mechanical Components

Begin by opening the machine’s backbox and examining all visible mechanical components. Look for any signs of wear, damage, or misalignment. Replace any worn-out parts and adjust misaligned sensors.

Step 2: Check Sensor Alignment and Cleanliness

Ensure that all sensors are properly aligned and clean. Use a soft cloth to wipe away any dirt or debris that may interfere with their operation. Test the sensors by manually triggering them to confirm they are functioning correctly.

Step 3: Update Firmware and Reset Settings

Check the manufacturer’s website for any available firmware updates. Follow the provided instructions to install the update. If the issue persists, consider resetting the machine’s settings to factory defaults. This can often resolve software-related problems without needing to replace hardware.

Step 4: Seek Professional Help

If after following these steps the issue still persists, it may be time to seek professional assistance. Contact a qualified technician who specializes in WPC pinball machines for further diagnosis and repair.

Conclusion

Encountering a WPC pinball machine where the ball is not being kicked out of the ball trough can be challenging, but with a systematic approach, you can identify and resolve the underlying issues. By inspecting mechanical components, checking sensor alignment, updating firmware, and resetting settings, you can get your machine back up and running smoothly.
