Troubleshoot Safely: A Guide to Maintenance Precautions

Though small in size, this powerful piece of equipment can still cause serious injuries if it is not maintained in a safe way. Before troubleshooting any problem, make sure that the water pump’s engine has had time to cool down if it was recently being used. This will eliminate the risk of burns and other unwanted hazards while fixing the problem at hand. It’s also important to make sure that the pump is in a safe location away from bystanders, preferably in an area with solid floors, ample ventilation, and access to emergency safety gear or tools that can keep injuries at bay.

Water Pump Issues: An Overview of Troubleshooting

When a Honda water pump doesn’t perform as expected, it’s usually due to either an engine problem or a problem with the pump itself. Though this might seem basic, the list of things to check, double-check, and replace, can be quite extensive. Be sure to have fuel, oil, tools, and standard replacement parts on hand before troubleshooting. Common replacement parts might include new hoses, new spark plugs, or other parts critical to routine operation.

1. What to Know When the Engine Won’t Start

Perhaps the most common issue faced by WB20T water pump owners is that the engine simply won’t start as expected. Though this is often a very aggravating issue, it’s one that can be solved by following a straightforward diagnostic procedure. First, start by checking that the engine has a sufficient amount of fresh, unleaded gasoline. Stale gasoline, or a low fuel level, will both keep the engine from turning on as expected. It’s also a good idea to check other basic settings, making sure that both the fuel valve and the ignition switch are in the “on” position.

If these checks and fixes do not resolve the issue, the next step is to check the spark plug. Make sure that the spark plug has been cleaned of any dirt and debris, ensure that it has been properly installed and gapped, and inspect for any damage that might be causing engine issues. If proper cleaning and installation of the spark plug does not solve the issue, try a new OEM Honda spark plug in its place. If even this does not resolve the issue, then the water pump will need to be checked and repaired by an authorized Honda technician.

2. What to Know When the Pump Won’t Move Water

The most frequent reason for a pump malfunction is that it has simply not been primed sufficiently prior to operation. Stop the engine, prime the pump as recommended in the Honda instruction manual, and attempt to use the equipment again. If the issue is not resolved, there are several other things to check that may fix the problem at hand. First, Make sure that the water pump’s hoses are tightly secured to the equipment, and ensure that they have not been damaged by prior use. If the hoses show significant signs of wear, replace them. If they’re attached loosely to the pump, tighten them.

Another common cause of pump problems is a clog in one of the hoses. If tightening the hoses did not solve the issue, remove them entirely and check for clogs in the strainer or somewhere within the hose itself. Clean any clogs that might be in place. After attaching the hoses, make sure that the suction head is placed low enough to take water into the pump. If these steps don’t fix the issue, take the water pump to a local technician for more extensive tests and repairs.
