<h2>How to Solve Your Triton Electric Shower Problems:</h2>
<h3>A newly installed T300si, when started the low water pressure light is on and there is only cold water from the showerhead, why?</h3>
<p>Check that the commissioning procedure has been carried out correctly as detailed in the fitting instructions. Check the inlet filter is not blocked and establish that water pressure and flow meets the specified minimum.</p>
<h3>Having reset the MCB my electric shower is now not heating the water fully, why?</h3>
<p>The most likely reason why the unit is not heating the water fully is that a heating element has failed. The elements can be tested for continuity using a multi-meter. If open circuit a new heater assembly is needed.</p>
<p>Note: If an element has failed other parts within the unit may have been affected it is therefore important to check all the electrical circuits in the unit for signs of failure.</p>
<h3>My electric shower is indicating low pressure what should I check?</h3>
<ul>
<li>Check isolation valves are fully open</li>
<li>Check inlet filter is not blocked with debris</li>
<li>Check minimum required water pressure and flow is available at the inlet to the shower.</li>
</ul>
<h3>My electric shower runs hot then cold (cycling), why?</h3>
<ul>
<li>The flow rate of water through the unit could be too low, causing the thermal cut-out to activate. Check there are no restrictions to the flow of water through the unit</li>
<li>There could be a possible sudden drop in water pressure, falling below the minimum required. This could be because water is being drawn off elsewhere in the house e.g. the washing machine, or a toilet flushing.</li>
</ul>
<h3>My electric shower will not turn off the water what should I do?</h3>
<ul>
<li>Check that the front cover has been fitted correctly with no distortion to the backplate</li>
<li>On units fitted with a commissioning link, check that it has been removed during installation (see fitting instructions for further advice)</li>
</ul>
<h3>My Triton electric shower is under warranty and has a fault, what is the procedure?</h3>
<p>If the shower is under warranty request an engineer visit via this site or call  0870 067 3333 to arrange a visit under the terms and conditions of the warranty</p>
<h3>The water flowing from my electric shower is cold/too cool, what can I check?</h3>
<h3>Is electricity turned on to the unit?</h3>
<ul>
<li>Check that the temperature control is set to the correct number for the time of year (you will need a higher number in the winter than in the summer)</li>
<li>Check that the power selector (if available) is set to ‘High’</li>
<li>On units fitted with a ‘Low Pressure’ indicator, check to see if it has been activated. If it has, then it is advisable to check for blockages in the inlet filter and/or have your mains water pressure checked</li>
<li>On units not fitted with a ‘Low Pressure’ indicator, pressure could still be the problem, so it is advisable to have this checked prior to an engineer call-out</li>
<li>Check that the front cover has been fitted correctly with no distortion to the backplate.</li>
</ul>
<h3>There is no water flowing from my electric shower, what should I check?</h3>
<ul>
<li>Is water turned on to the unit?</li>
<li>Is electricity turned on to the unit?</li>
<li>Is the inlet filter blocked?</li>
<li>Are the front cover and any start/stop connecting cable fitted correctly?</li>
</ul>
<h3>Water from my electric shower is not getting hot enough, why?</h3>
<p>Check the temperature control and power setting is on the correct setting for the time of year.</p>
<p>Check the temperature control (flow control valve) is regulating the flow of water through the unit, there should be a noticeable reduction in flow when turning towards the hotter settings.</p>
<p>Using an electrical test meter the following electrical components can be checked for continuity:</p>
<ul>
<li>Heating elements</li>
<li>Micro-switches</li>
<li>Thermal cut-outs</li>
<li>If the unit is electronic then voltage tests have to be carried out on the PCB/s (printed circuit board/s) in the unit.</li>
</ul>
<h3>Water from my electric shower is too hot, why?</h3>
<ul>
<li>Check that the Stop Tap is fully open</li>
<li>Check that the sprayplate of the showerhead is clean. Check if an acceptable temperature is achieved by removing the showerhead from the shower hose</li>
<li>Check the internal lining of the shower hose is not collapsed</li>
<li>If the shower is delivering a flow of less than 5 litres/minute on a temperature setting of ‘1’, then check for blockages in the inlet filter. Use a bucket and stopwatch to check flow rate</li>
<li>If the problem is occurring during a period of hot weather, then you may be experiencing high incoming ambient water temperatures and /or borderline water pressure. Try setting the power selector (if available) to ‘Low’ and adjusting the temperature control to suit.</li>
</ul>
<h3>What is a PRD (pressure relief device)?</h3>
<p>The PRD is a safety device designed to relieve abnormal pressure from within the heater assembly of an electric shower when a restriction occurs on the shower outlet i.e. blocked showerhead, collapsed shower hose. If activated it will be necessary to fit a new one.</p>
<p>When I turn on my electric shower water starts leaking out from the bottom of the unit, why?</p>
<p>If water is leaking from a clear plastic tube or small plastic elbow in the unit, then the Pressure Relief Device (PRD) has been activated. The most common reasons for the PRD to activate are that the showerhead has become blocked or there is a restriction in the shower hose. A replacement can be ordered from our online spare parts store or by calling 0870 067 3333</p>
<p>If the water is not leaking from the clear plastic tube, then isolate the electricity supply to the shower and call 0870 067 3333 for advice.</p>
<h3>Where is the filter situated in a Triton electric shower?</h3>
<p>The filter will be found in the inlet connection. In some units it will be necessary to disconnect from the water supply to access the filter.</p>
<h3>Where is the serial number located on a Triton Electric shower?</h3>
<p>A rating label is located on the underside of the unit, which includes the model name, kW rating and the manufacture date code (ACCEPTABLE FOR WARRANTY REGISTRATION). Inside the unit there is a further product-rating label, which has the same information and also the serial number.</p>
