Top Troubleshooting Tips for Your Dishwasher
Determining the cause of a dishwasher malfunction can be among the most difficult of plumbing problems to solve. Following are some troubleshooting tips to help you decide if you can solve the problem or need to call for help.
Dishwasher Won’t Fill Up
If the power is on, but the water won’t fill up, check the stop valve for the hot water supply under the sink. Make sure it’s turned on and open all the way.
It’s also possible the float is malfunctioning. When the dishwasher is cool, turn off the power and find the float, a small plastic dome or cylinder near the tub’s base. Lift it and clean around the tube (you may have to remove an access panel to disconnect it). Replace the float.
Other malfunctions causing the dishwasher not to fill up could be in the door switch, door latch, drain valve, drain valve lever arm or water inlet valve.
Power Won’t Come On
Make sure that the power is on, the door is firmly shut and that the control is on. Then, check the power cord to see if it has a reset button. Push the reset. Then, look at the electrical panel to see if the circuit breaker that leads to the dishwasher is tripped or if there’s a blown fuse. If it’s tripped, switch the breaker off and back on, or replace the fuse.
Other possible problems could be a defective door switch, selector switch or timer. Call for professional repair.
Dishwasher Won’t Drain
If you find substantial amounts of water in the tub after a cycle, the cause can be a malfunctioning pump, backed up drain lines, or a drain hose that isn’t working.
Dirty water spewing from the air gap can mean the drain line is clogged. Take the cover off the air gap, a short domed cylinder at the back of the sink, and clean it with a stiff wire. Straighten any kinks in the hose.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
